When I first got my chickens, I got four. One day, one of them (Hidey) started looking ill. She was staying on her own and not moving as much, and not eating very much and her eyes were red. We assumed this was because she was old. A few days later, she died. About a year later, another chicken, Peckles, looked ill. We knew she was going to die, but we weren't expecting her to die when she did. Not that long after, I got another chicken. This one was gray, unlike all the others which were Rhode island reds. I got three more chickens from my cousins. Not long after, a chicken called Naomi look quite ill but didn't' die. Soon, one called Emily died. Shortly after, one of my chickens called Speckles died. Now one called Pandora is looking ill. I want to find out what is wrong with them in case I can help. Note: my chicken coop is made out of chicken wire and has no roof and the chicken house is fine.
