One of our hens, the one in my avatar, her name is Black Sheep, is sick She had a greenish poopy bum and didn't come out of her coop for 2 days. We noticed she was also breathing heavily. We took her aside and washed her with warm water and soap, got her all cleaned up. Then we smeared her with vegetable oil, as thats what my man said should be done. He read it somewhere. We also went to the feed store and got a Stressed-out, formula with vitamins and electro lights and added it to there water. Today she was out and about most of the day but just in the run and wouldn't free range. She is still lethargic and will only walk about 10-15 feet and then sits down. The other chickens are not picking on her at all but more like babysitting. Most of them are older, about 5-6 years old. Some are hanging out with her and keeping her company. She is eating well and drinking plenty and does seem a wee bit better. not breathing heavy anymore. I am worried because now i noticed 2 other hens have a poopy bum as well. HELP!! And thoughts?
