Good evening.. About a month and a half ago my arucana hen was found dead in my coop.. I figured she was just old.. This week one of my 4 year old RIR's was acting odd, walking slow, did not drink when water was in front of her, etc.. I bought some liquid vitamins for poultry and gave her some..also cleaned my coop thoroughly thinking maybe something in the coop was making her ill.. I clean the poop out each day.. the next day, Tues, she was dead in the coop when I went in the AM to let the girls out.. I took her to a vet for an autopsy and he said she had peritonitis in her abdomen.. No coccidiosis.. and looks like she was not assimilating any food as she was thinner than she should have been.. They have lots of food available, treats, grit, oyster shells, etc.. Now tonight, another one of my girls is acting the same way... she stood by some watermelon very still and took a few nibbles.. had all she could do to get in the coop and now she is on the floor of the coop and I am thinking I may find her dead in the AM! :-( The vet did mention I could worm all the girls as that has never been done.. What on earth is going on in my coop??
