This is the first experience I've had with a "sick" chicken and I need some advice. I have a GLW that for the last 2 days is staying away from the other birds, she never sits but only stands, has a poopy backside and holds her tail down. We segregated her this afternoon. She immediatly ate and drank when she got put in the dog crate. She won't go on the roost and stands all night on the floor. I don't know if she has been laying eggs because I have 5 hens and they all use the same box with no way to determine which bird is laying which egg. The hubby thinks it may be coccidiosis <spelling?> but from what I've read it usually doesn't impact 10 month olds and it is the winter. They have 10 acres to free range on but hang out in the front yard grass not the pasture. The other ones seem to be doing fine. Any help or advice on what to do would be appreciated!
