We have a Light Brahma who will be two in April. She has always been healthy, but we noticed on Sunday that she seemed kind of weak and out of sorts (closing her eyes while foraging). Upon picking her up we discovered she is skin and bones. You can't tell by looking at her as she has a full coat of feathers for our NH winters. She is eating (pellets, meal worms, yogurt) and drinking water, as well as eating snow (odd?). She can't seem to make it up to the coop at night, rather laying on the cold sand in the run, so I have been going out after dark and putting her in the coop. I doubt she could stay on the roosts so I just put her on the shavings on the floor (it's a raised coop above a sand filled run). She makes no attempt to get away from me when I pick her up, which is abnormal, she is tame enough, but doesn't like to be picked up. She is the first one at the door in the morning to see what I've brought for them though. I am thinking of setting up a cage in the house for a few days? Any suggestions? We are entering our fifth year of keeping a small flock of hens (6 right now) and we have been lucky with illnesses.
