I'm going through the same thing. Red had a toe that started turning black about three years ago. My bird vet thought it had come from some injury;
she amputated half of the affected toe and he did well. Then the rest of the toe started turning black and she amputated the rest of it. Since that time
his other toes turned black and he now has only one toe on his left foot and two on the right. He is obviously in a lot of pain and the other rooster(his son)
beat him up and took his hens. It's so pitiful and my heart breaks for him. He limps badly and is obviously in pain but I don't know what to give him. Today
I brought him in the sun room and put him in a large dog crate with a thick soft bed of straw. He looked so relieved he laid down and took a nap. I went
to
Tractor Supply and bought him some mealy worms. Right now he seems to be relieved that he's getting one-on-one care and lots of petting. I noticed
that now there's a dime-size black spot on his upper right leg. I know that he's going to have to be put down but I am going to make his last days as
comfortable as possible. He has been a wonderful boy and has given us many beautiful chicks. He was always sweet to the hens and babies. My husband
thinks I'm silly because I've been crying all day. Our chickens are free range and I love looking out the windows and seeing them everywhere. All of them
will come up to be petted. I'm going to research this problem to see how common it is. Thanks for listening. Janice Murphy
