One of my buff hens has been acting a bit weird for the past three days. She is the only one of my flock that hasn't molted yet, but today I noticed that she's looking a bit tattered, so I think she may be starting to molt. She's an 18 month old LF buff brahma hen. They free range every day, have layer pellets and oyster shell available 24/7, plus treats. No mites or signs of any illness. She's not eggbound that I can tell. Three nights ago she went to roost about an hour before the rest of the flock. Since then she has spent her days just sitting in the chicken yard and not foraging with the others. She sits in one spot for most of the day and goes to roost a little early. I've noticed her sleeping quite a bit during the day. Do some hens just feel bad as they start to molt? UPDATE: Her crop feels fine, but mostly empty. Her bottom feels swollen, but still pliable, not rock hard and I don't feel anything that even remotely feels like an egg. Her comb and wattle color is good. She turned down a treat of bread, which is a real shocker. Any ideas?
