I had 9 5 week old white rock chicks, dh fed them some cracked corn and layer pellets, I told him not too but he did anyway now I have lost 4 and two more on on their way out. a friend of his at work said that his nephew feeds his yard mix (layer pellets, a bunch of seeds, and whole corn and cracked corn ) and never gives his any grit or anything else I told him not to believe everything they say but he does and now my chickens are dying there is blood all over their pen and blood all over their bums. how can I keep the rest from dying? I only have 5 left and 2 of them are dying. PLEASE HELP ME SAVE MY CHICKENS!!!
