Posting this for a friend. One of her hens started not looking quite "right", kinda puffed up on Sunday night and was dead on Monday morning. Now today another hen is "off" looking. Her horses were being treated for colic. Vet came on Friday and the horses received tranquilizers and meds. Butte and Banamine sp? Very acute cases treated aggressively. The hens mess around in the manure pile, could this have something to do with them being sick and dying? Thanks for your help.
