I just recently bought several Easter egg and Dominique chicks. I have had them for a week, and now most of my easter eggers are gone due to a strange illness. That just stand or sit out in the brooder and eventually fall asleep and die. I have been giving them general antibiotics, but nothing is working; they keep dying off one or 2 at a time; very few of my Dominiques have been affected. Does any one have any suggestions so I won't loose all my Easter Eggers??
