One of my adult hens is acting strange - staying off by herself in a sheltered area behind the coop. I've looked her over, but can't find anything physically wrong with her. At first I thought she might have been chastised by the other chickens that are higher ranking, but this is day two of her acting a bit off and I'm starting to worry. She looks totally fine, except perhaps for her comb being more rosy-colored vs. bright red. I checked her this morning for a stuck egg, but didn't feel anything out of the ordinary. 1) What type of bird , age and weight. A 2 year+8 month old LF buff brahma hen, approx. 6 lbs. 2) What is the behavior, exactly. Just not being active, staying off by herself. She is going into the coop at night to roost. 3) How long has the bird been exhibiting symptoms? Today is the 2nd day. 4) Are other birds exhibiting the same symptoms? No 5) Is there any bleeding, injury, broken bones or other sign of trauma. No, although her comb is rosy tinted, not bright red like the other hens in production. 6) What happened, if anything that you know of, that may have caused the situation. Nothing 7) What has the bird been eating and drinking, if at all. I've seen her at the feeder and waterer, but she is not joining the others at treat time. 8) How does the poop look? Normal? Bloody? Runny? etc. As far as I know, fine. She does have a bit of yellowish poo stuck to her butt fluff. The flock was wormed with valbazen in November. 9) What has been the treatment you have administered so far? None, so far. 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? Home treatment only. 11) If you have a picture of the wound or condition, please post it. It may help. 12) Describe the housing/bedding in use Birds free range daily. Our temps. yesterday were in the 70s, but only the 40s today. The birds are locked up in a draft free, predator proof coop at night. I use pine shavings with the DLM. I added DE and fresh shavings yesterday, but she was acting strange before that. Any input would be greatly appreciated.
