I tried to find my last thread that was about our black silkie that seemed to have joint trouble but could not. I just wanted to thank everyone for all your help. we finaly had to put black chicken down last night. it was so bad it could not even get off its back and I just did not want to see it suffer anymore. my husbend put it down for me I just could not do it. we tried so hard to save it and it would get better and be walking then all the sudden be reallybad again. it had gotten so thin and was just so sad all the time. the whole coop is sad we think they are not smart but they know when one dies...I think they even miss it.
