I have a 3 year old Buff Orpington who is not herself. She is molting and this is her third time molting. While you can barely tell she's molting by looking at her, she's always had a rough go of it and been moody and keeps to herself in a safe corner while she molts. But my gut tells me something else is wrong. She's staying on the roost after the other 5 hens go out to forage. I lifted her down yesterday and she rested back on her haunches and almost sat upright. I gently pet her for a bit and after several minutes, got up and walked normal and went to the feeder to eat. Today, same thing, still on the roost an hour after the sun was up. I put her out in the run and this time she just walked normal and went to go eat. But more slow that normal. I'll run a dropping to the vet to test for parasites and salmonella later today but my gut tells me that something is internally wrong. She's not laying so I don't believe it's an internal egg. Her poops are normal looking and she's got an appetite. This bird has ALWAY been very timid and is terrified of the other birds even though no one picks on her. One hen did a long while back but I got rid of that bird two years ago. But I think she remembers. Anyway, I'm just wondering what others thing might be up and if 3 years is old. I think it's middle aged and that she could have cancer or something internally wrong. I won't go through major hoops to save a bird. But I would do a round of wormer or antibiotics if that seemed in order.
