Hello all, I have a "black australorp" hen about 5 months or so old. The last week she has been acting a bit more lethargic than normal. She is an only backyard (underground) hen. She has a coop with roosting perch and is let out everyday at 2pm to run free in my yard. She routinely eats whatever is in my garden (mostly tomato fruits) and the usual bugs. I do not use pesticides she is the bug control. Her comb and face seems to have lost all its color its almost white. Her poops seem normal though have decreased significantly in size with each day. She is still eating small amounts of pellets and is drinking. I started her on Tetracycline Hydrochloride on Thursday night just in case as that is what the guys at the feed store recommended. She is drinking the meds in the water in small amounts and I am providing un-medicated water during the day. I moved her indoors to a large dog crate with heating pad on Thursday as well. She follows me around the house sloooowwwllyyy and she is interested in things still like pecking around and noises and scratching. She does not seem to have any balance problems though she can walk perch and turn around though she does not seem to have the oohmf to get her but up onto a perch but she can jump down fine. Any thoughts on what could be the cause?
