一、夏日养鸡降温妙计，猪粪蚯蚓养殖技艺并进；体重标准一目了然。下面六项，请引起高度重视：
1、注意鸡舍通风降温
密闭式鸡舍可安装风扇或吊扇，纵向通风比横向通风换气效果更好，夏季鸡舍内的风速以1.0米/秒~1.2米/秒为宜。
湿帘是当前规模化生产最经济有效的降温措施，纵向通风结合湿帘降温预防热应激效果更好。开放式鸡舍可以安装风扇，打开所有门窗，以促进空气流通。
2、注意喷水降温
鸡无汗腺，其体内产生的热量只能靠呼吸散失，对高温的适应能力差，因此需保持每日6-8个小时的喷水时间。
当舍温超过30℃时，可用高低雾量旋转嘴喷雾器，将凉水直接喷洒至房顶或鸡体，每2-3小时进行一次，可使温度下降6-8℃。
3、注意调整饲养密度
一般笼养每只需0.4平方米，每笼3只。平地散养每平方米可饲养3只~5只。大群饲养每群200－300只，以利于内外空气流通。
不同龄期的鸡适宜密度：7-14日龄为每平方米25-30只；21-28日龄25-15只；35日龄至出栏10-5只。
4、及时清除粪便和垫料维护卫生
夏季Chicken dung极易发酵诱发疾病，因此必须定期清理（至少隔天）以及保证肉Chicken有一个安宁环境。
五点请记住：
5、高效光照管理与减少活动时间
早开灯晚关灯，加大早餐或分多次均匀供应，让Chicken在白天享受凉爽时刻食物。此外，在午后停止供餐减少活动，同时确保全天新鲜清洁饮水。
六点要留意：
6、疫病防治工作
二、雏Chicken体重标准？
刚出生的小Chicken四五十克正常不疑惑？
三、一探原因：为什么雏Chicken甩头？
Head-shaking in Chicken is a symptom of Infectious Coryza, caused by infection with Haemophilus parasuis.
Infectious Coryza is a contagious respiratory disease that affects chicken groups, causing inflammation of the nose and sinuses, nasal discharge, facial swelling, and conjunctivitis symptoms.
It causes economic losses due to growth delays, increased mortality rates and decreased egg production.
Four: Clear-braised Chicken recipe?
Firstly wash the chicken clean then chop it into bite-sized pieces.
Soak the chopped chicken in water mixed with salt for 15 minutes before draining it.
Prepare ginger slices and green onions as garnish.
Pour enough water into a pot to cover the chicken pieces then add salt and Shaoxing wine (or dry sherry).
Bring to a boil then remove scum before simmering over low heat for 30 minutes.
Add soaked Chinese angelica (dried or fresh) during the last 8 minutes of cooking along with additional salt and white pepper if desired.
Five: How to inspect chickens?
Examine their spirit status - whether they are healthy-looking or not; check if their feathers are clean or dirty; ensure beaks, legs & toes are straight; observe any signs of illness or weakness such as runny eyes or labored breathing;
Feel them - assess their body condition (fatness), temperature & bone development plus abdominal softness & yolk absorption quality;
Listen - examine their calls - clear sounds indicate good health while weak ones may suggest sickness;
Six: What equipment does one need for brooding chicks?
A cardboard box lined with paper towels provides insulation until they can regulate their own body temperatures around four weeks old when they become more self-sufficient at maintaining warmth themselves. Adjust humidity levels also helps maintain chick survival rate.
Seven: What should I feed my chicks?
Chicks thrive on specialized commercial feed designed specifically for young chickens but can also be fed rice bran mixed with finely chopped vegetable scraps in water if preferred.
Eight: Initial drinking water considerations?
Initial drinking starts after hatching between day one through three when meat breeds drink most frequently within hours after emergence from eggs due to high fluid loss during this period. Provide ample drinking stations preventing overcrowding which could cause drowning accidents while adding sugar syrup (5% ~ 8%) antioxidants vitamins electrolytes may enhance initial hydration experience
