My 10 month old barred rock seems to have come down with an illness. Her poop is milky white with few chunks, she is very lethargic, but she is eating and drinking what I am giving her (fruit and fruit juice). What worries me is I had a beautiful silver laced wyandotte that died a while back bearing the same symptoms. They have both been treated with Corid, so I'm not sure she could have cocci. Please help!! Thanks.
