I have a rooster that has frostbite on his comb and wattles that has become lethargic. This morning I found him laying on the ground and he was very limp when I picked him up. He doesn't want to stand but when he does he's got a bit of a limp. His feet don't look frostbitten to me but I'm sure it's a possibility. I have him laying on my lap to warm up a bit. He tries to eat but would rather sleep. I got him to drink a little bit of water, is there anything else I can do for him? I also tried to give him a little baby aspirin which he normally eats from me no problem but he would not eat it today.
