I'm slightly new with raising chickens, I've had 3 for a year and a half, and another 3 for six months. One of my chickens, a barred rock named Raven, started to molt. It's not a huge molt, where she looses all her feathers at once, it's a few-here-few-there kind of thing. Anyway, she's been acting very strange. She's very lethargic, she's not interested in food, she runs away from me and the other flock members. I did some research, and a group of flock owners say that this is normal. So, I let it slide for the day. I checked on her this morning and her crop is very soft, almost like a half full water balloon. So, I did more research... I'm thinking it could be Coccidiosis, but I'm not sure. There are a few chickens who've had bloody droppings, but that, to me, is normal because I have the 3 that just started laying, similar to the my first 3 when they first started, there were a couple strange droppings. Should I be worried about this? Should I quarantine her for a few days/week? Should I get her some antibiotics?
