[I've already posted about another problem one of my hens was having today and I don't want to make it seem like I don't care about my chickens here. This is my first year having chickens and I love them very much. So any sort of unknown bad thing happening to any of them really worries me because I don't want to unknowingly be neglecting them.] A few days ago I noticed my rooster had a swollen toe. I thought it might go away but I've kept an eye on it and it's gotten much worse. It's spread to his other foot too. Parts of his feet and legs have become very red and so have the feet of some of my hens. Are they all suffering from frostbite on their feet? I think my rooster has some sort of infection regardless. Here are photos of his feet right after I soaked them in some warm water with Epsom salt today.
