My white leghorn developed some yellow crusty patches on her comb yesterday. I thought she had some food stcuk to it, as I had given her part of a cooked acorn squash yesterday AM .She stayed in the laying box alot, but didn't lay an egg. Today the crusts are back, and she is just standing , not walking around. Don't hear any respiritory problems. I wrapped her in a towel and brought her inside. She naps, but wakes up when i put her down. Any suggestions ?
