NEW EMERGENCY! We had a sick chicken last night. She couldn't stand and would just flop around. The others basically attacked her and was horrible to watch and when we tried to intervene it was too late and she was suffering so my poor husband had to euthanize her. She has been like a member of our family for 4 years. Would old age cause the symptoms above that I listed or should I be concerned for the other 8 chickens that we have? They have run of a large building. Fresh water and food daily. Building is cleaned and fresh straw put down weekly. Their are 8 laying boxes but they only utilize 3. Other chickens seem fine right now but want to make sure it stays that way. We have noticed that she has slowed considerably down and goes into roost earlier than all the other chickens. All our chickens run the acreage during the day and roost in the building at night. Just the day before she came up to the house with the rest of the chickens for their daily treat! She seemed fine then.
