Hello, about three days ago when i let my 4 girls out of the coop one did not come out. She laid an egg around noon then left the coop and joined the others, the next day she did the same thing but i noticed she was acting weird, lethargic and not coming to eat the evening treat i always give them This morning she again didn't get out of the coop with the rest of the girls, I went to the feed store and got some antibiotics and has been giving them to her orally. She is very lethargic, not keeping her eyes open, tail is down and runny poo. I then noticed her feet, can someone tell me if this is indeed bumble foot. If so then im thinking this might be the issue. Any advice would be great since I am very green and have only been a chicken owner for two months now.
