This year has not been a good chicken year for me. I've had a hen die early, and I'm fighting mites. On top of it all, my oldest hen Ash is getting very old and has an abcess/bump on her face right next to her eyeball. (If anyone could tell me what that is, I'd really appreciate it.) She has this adorable "crow" in the morning that she does on top of the waterer, but today she couldn't make the jump and yesterday she fell down after I had been holding her and put her back down again. Is she suffering, and if so, should I put her down?
