My chickens are getting layer feed. But my Rooster acts as if his feet hurt. I picked him up and they look good. He is missing almost all of one claw, but it doesn't look bad. I had had some lameness of one hen a while back, and after some research decided to switch to a high protein grower feed. That did cure the problem completely. After feeding maybe 6 bags of the grower(I think that took 2 months), I went back to layer. And today I notice the rooster being a bit lame. Why is this happening? It is cold here, but not horrid. It was 6 degrees at 8:30am, it is now up to 20 at noonish. I have ducks and chickens. The chickens are light Brahmas (11) and then 4 easter eggers. None of the EEs have had problems. Feed and water is given free choice. I use heated waterers, so the water is never too cold. The Brahmas have such giant feet, especially when compared with the EEs, it is hard to believe they are having any problems with the cold. What is going wrong? Should I switch back to the layer?
