I have a brooder full of 10 day old chicks. Many are getting leg paralysis. Too young for mareks and they are vaccinated, they have plenty of bedding although this looks like spraddle. What is it? I suspect a ,mold toxin from wet bedding but more are continuing to come down with it even though we got rid of the mold. Also, leg problems dont seem to be a common problem with mold exposure but it is mentioned. I move about 2000 chickens though the barn each year and dont know what is up. Anyone have an idea?
