My hen is 4 1/2 months old and has swollen feet and legs that seem to be oozing blood. The bottom of the feet appear to be intact, no brown spots or cuts that I can see. Her comb is also floppy. None of the other chickens in the flock have this. She is still walking around, eating, and drinking normally as far as I can tell. The only recent change is I changed their bedding from wood shavings to straw. We live in a dry, warm area so the straw and coop are not moist. I clean it weekly and change the bedding. We haven't had any nights below 37 degrees. Any ideas about what is? and what can I do? Do I need to separate her from the other chickens? Thanks!
