How to hatch chicken eggs? Spring is the season when the weather gets warmer each day. For many animals, new life begins in Spring.  🍀Chicken factsA chicken is a kind of domesticated [dəˈmestɪkeɪtɪd]家养的bird. It is raised widely for its meat and eggs. They are usually kept by humans as livestock[ˈlaɪvstɑːk]家畜, which means it is kept for its meat and eggs. Most breeds [briːd]品种of chickens can fly for short distances and some roost [ruːst]栖息in trees if these are provided. A male chicken is called a rooster or a cock (short for cockerel). A female chicken is called a hen.A young chicken is called a chick. Like other female birds, hens lay eggs which can hatch into chicks. When raising chickens, a farmer needs to build a chicken coop [kuːp]（关鸡等的）笼子(like a little house) for the chickens to roost (sleep) in. They also need a run 栏舍or yard where they can exercise, eat, and drink. The chickens also need to be protected from predators [ˈpredətər]捕食性动物such as foxes, which is often done with fences. Chickens can also be farmed intensively[ɪnˈtensɪv]集中的密集的. This lets farms make a lot of chicken meat, and eggs, but this is not as good for the chickens. 🍀The growth of a chick 了解小鸡怎么长成的 it only takes three weeks for eggs to turn into chicks.  Chick deveopmentDay1- eyes begin to formDay2- heart begins to beatDay5- formation of reproductive [ˌriːprəˈdʌktɪv]生殖的繁殖的organsDay8- feathers begin formingDay10- beak starts to hardenDay12- toes fully formedDay14- embryo([ˈembrioʊ]胚胎) turns head towards 🍀Choosing fertile eggs 挑选受精鸡蛋 1 Make sure they're fertile eggs 受精卵The eggs we find in grocery [ˈɡroʊsəri]食品杂货店stores are not fertile and cannot be hatched. To hatch the eggs must be fertile, this means they need to be collected from hens that have been housed with a rooster for breeding. We may be able to buy fresh farm eggs from the internet. It's very convenient. But when the eggs are more difficult to hatch if they are treated very roughly during shipping. 词汇解析：fertile: [ˈfɜːrtl]可繁殖的。able to produce babies, young animals, or new plants roughly:not carefully or gently  2 Select fertile eggs wisely. 挑选受精蛋 Avoid excessively [ɪkˈsesɪv]过度的large or small eggs, or misshapen [ˌmɪsˈʃeɪpən]畸形的eggs. Large eggs hatch poorly and small eggs produce small chicks. The cracked eggs cann‘t be hatched. 3 An egg contains a male or female chick?能孵出母鸡还是公鸡？ An important point to keep in mind is that your eggs will generally hatch out in a 50:50 mix of males and females.  Understand that there is no way to know whether an egg contains a male or female chick before the egg has hatched.  you may hatch 7 males out of 8 eggs. <h1>🍀Using an Incubator 如何用孵蛋器孵蛋</h1> Day 1: Setting The Eggs An incubator(孵蛋器) is an enclosure [ɪnˈkloʊʒər]围场which has controlled temperature, humidity [hjuːˈmɪdəti]湿度，and ventilation([ˌvɛntəˈleɪʃən]通风).  1 Choose a location for the incubator.Avoid direct sunlight.Connect the machine to a dependable electrical source.Keep the incubator out of the reach of small children, cats and dogs. 2 Adjust the temperature and humidity according to the instruction. 3 Set the eggs. Place the eggs carefully into the incubator. Make sure the eggs are lying on their sides. The larger end of each egg should be slightly higher than the pointy end. This is important as the embryos can become misaligned [ˌmɪsəˈlaɪnd]方向偏离的、未对准的if the pointy end is higher and may have difficult pipping[ˈpɪpɪŋ]破壳而出, or breaking through the shell, when it comes time to hatch. 4 Record the date.Chicken eggs take 21 days to hatch when incubated at optimal [ˈɑːptɪməl]最优的temperature. If it is Day 21 and your eggs haven't hatched yet, give them a couple of extra days, just in case! Day 2-18: Turning The Eggs 5 Turn the eggs daily. When turning eggs manually[ˈmænjuəli]手动的, your hands must be washed and clean to avoid transferring bacteria [bækˈtɪriə]细菌and oils onto the surface of the egg.Keep turning the eggs until day 18, and then stop to allow the chicks to position themselves properly for hatching. 6 Candle the eggs after 7 to 10 days.Candling the eggs is when you use a light source to view how much space the embryo occupies within an egg. After 7 to 10 days, you should see development of the embryo. Candling allows you to remove eggs with embryos that are not viable[ˈvaɪəbl]切实可行的、可生长发育的 By the 18th day, the chicks have developed and are getting ready to hatch out.  On day 18 stop turning the eggs. At this point in development, the chicks are positioning themselves inside the eggs for hatching. Day 21: Baby Chicks Start To Hatch 7 Prepare for the hatch. Stop turning and rotating eggs 3 days prior [ˈpraɪər]优先的、在前面的to thehatch date. Most viable eggs will hatch within a 24 hour period. Normally chicks start to hatch on the 21st day of incubation. But if the eggs were kept a bit to cool before you started to incubate it can take a bit longer.So don’t give up if they haven’t started hatching on day 21. It’s also possible for them to start hatching a day or 2 early if the incubator was a bit warmer then normal. When chicks first start to hatch you will see a small opening in the middle of the egg. This is called pipping [ˈpɪpɪŋ]out.Slowly the chick will work its way around the egg working to make a crack line around the middle before finally pushing the eggshell open.This process can often take 24 hours  It’s important not to help chicks during that hatching process as much as possible. During this time the chicks are slowly absorbing the egg yolk and blood vessels may not have dried up yet.Pulling the eggshell off to soon can cause bleeding that can kill the chick.Leave the chicks in the incubator until they have dried off.I know you may feel rushed to get them out of there but they are still wet and the safest place for them to be right now is in that nice warm incubator. Chicks can stay in the incubator for up to 2 days without worry.This is a good thing because the more you open the incubator to remove chicks the higher the chance of harming chicks that are still in the process of hatching.Opening the incubator can cause a change in temperature and humidity that can make the membranes [ˈmembreɪn]膜around the hatching chicks dry out. This makes it much harder for them to finish hatching.So be patient and let the hatch finish undeserved as much as possible. Once the chicks have all hatched and dried off you can move them to the brooder育雏器 小记：哎，由于第一天晚上没有照灯，小鸡着凉拉稀了，第二天晚上有一只小鸡半夜惨叫，然后死掉了……一整天心情不好。出于对生命的敬畏，下一次再也不轻易孵小动物了。脑海中一直回响小鸡的惨叫声，罪恶感深重！ 不过养的好的话，毛茸茸的小鸡崽真的挺可爱的，偷偷观察他们也很有意思，原来小鸡睡觉时也是东倒西歪的，不过小鸡真的是太能拉shi了…… 亲自孵小鸡，看着蛋变成鸡，不由自主的会感叹生命的神奇！！！
