Could anyone venture a guess as to what's wrong with two of my hens? I have a flock of 6 Cochins and 5 Ameraucanas. Everyone else seems fine but I noticed two of the Cochins were hesitant to exit the coop into the yard this morning and seemed to be very uncomfortable walking... they'd rather just sit on the ground in the shade than run around iwth the others. Also feet look very strange- normally are yellow and smooth, now are white, puffy, somewhat scaly. No marks on combs or faces, though. I put them back in the coop so they could be alone and rest. I did get them to eat a hard boiled egg and some watermelon- haven't seen them drink yet. Not interested in scratch or regular feed. I'm worried- these are family pets. Again, any suggestions? Could it be avian pox? We have a lot of mosquitos right now, plus doves, quail, finches at feeders in the same yard.
