1) What type of bird , age and weight (does the chicken seem or feel lighter or thinner than the others.) 2 year old Buff Orpington hen, currently molting, but has been thin for about 6 months. 3) How long has the bird been exhibiting symptoms? ~6 months maybe longer 4) Are other birds exhibiting the same symptoms?no 7) What has the bird been eating and drinking, if at all. She seems to eat well, her crop feels full when I feel it and it seems like it should be, not squishy. Currently the whole flock is getting Flock Raiser (22% protein) because only 4 hens out of ~45 are laying. The flock free ranges 3-4 days a week and they get sunflower seeds, a small amount of scratch and leftovers as treats. 8) How does the poop look? Normal? Bloody? Runny? etc.poop looks normal not runny 9) What has been the treatment you have administered so far? none 10 ) What is your intent as far as treatment? For example, do you want to treat completely yourself, or do you need help in stabilizing the bird til you can get to a vet?I'd like to figure out why she is thin. 12) Describe the housing/bedding in use. 10x20 coop, large run (100x100?) and free ranged 3-4x a week or more. Pine shavings for bedding. I have had stool samples done tested by a vet every 2-3 months and no parasites are found. She has no external parasites that I can see. She never really layed well, maybe 1x a week at her best and I'm not really sure when she layed last. She seems like she is a little weaker than she has been but its hard to tell. No nasal discharge, eyes bright, feathers shiny and in good shape. Feet have been checked for bumblefoot, crop nice and full, not squishy. I read somewhere that internal fungal infections could cause thinness but I am totally stumped.
