Had this problem a few days ago thought was doing better. Not entirely sure she has layer an egg. Gave her a soak in the the tub and took a picture of her vent. I believe she is a Starlight chicken going a year old. I did give her a calcium tablet before the bath nothing yet. Anything else I can do. She is very lethargic. Picture is a little graphic. But thought I should include. Again this is my qst sick chicken and 1year chicken keeper. She also whine a little.
