have a black silkie rooster his name is Bert. We have been thru leg mites, His legs look great now, but he doesnt. He has been withdrawn from the flock for about 4 weeks, thought it was because of new White rooster I introduced. then noticed he was loosing the down feathers off his neck. Now his neck looks like old chicken skin real yellow and he is a silkie so he should have blue skin. His was always more black than blue. Now all his skin is white, his comb is black instead of red. His ears are silver instead of blue. He is not going to make it but I am just wondering what he may have to make sure the others dont come down with it. Everyone else seem fine. The other bird who had the worst legs of all Maxine she is fine and her legs are great now too. I have tried the Vetrx from TSC and oiled his neck with it for the last several days. I have him in a tote in the house because its cool here today but he is just sitting with his head face first on the bottom, cant get him to eat or drink and He isnt passing anything. I have had him a year he was full grown when I got him but I dont believe he is over 2 but not sure.....anybody have a clue??
