2 of my chickens were attacked by a dog, one chicken has made a seemingly well recovery. She is like one of the pack again. The other chicken doesn't look so good, she says in the shed (where I have been keeping the two sick chickens) almost all day, and she hasn't been eating much except for what I give her by hand. She has started to walk with a limp.. I don't want my chicken to be in pain, but I don't want to kill her... Also, I have been keeping the two sick chickens away from the others during the night, because the healthy chickens were pecking their soar spots, but today I saw the chicken that is getting better peck the other chicken on her soar spot.. Should I put the chicken that is getting better back in the coop with the other chickens? Should I just put down my chicken that isn't doing to good? How do you know when it is time to put down your chicken?
