This morning I found a bunch of blood on the hens poop board, not bloody poop, just a big gob of blood- also looked like tissue. It's from my buff rock, she's very big and has only laid 1 little egg, a few days ago. All the others are laying, they are all 5 1/2 months old. Yesterday she was eating and drinking though I noticed her laying down a lot. She went into the nest box for a while but didn't lay an egg. Other Symptoms: can't walk straight, falls to the side or forward quiet not eating or drinking her abdomen feel a bit bloated and squishy I have her now in the house. What should I do?
