I don't know what happened!! I have 25 CornishX Chick in a hutch type enclosure and when I went to feed and water them today I found two chicks had bloody holes. They are next to the anus and are oozing blood. I don't think it's from pecking because I've never seen any of these chick peck for some reason. The holes are about the size of a dime! What do I do?
