Should I be worried about watery poop from my 10 day olds. I have 5, 10 day olds mixed with 2, 3 day olds. They are eating, drinking, and playing fine. This is my second round of chicks. The brooder is new. They were vaccinated for meraks from the hatchery but I do have them on medicated food (is this ok?)? They have had access to outside b/c I have placed the brooder out for the past 2 days because of the hot weather. They are shaded and seem to really enjoy being out. The watery poop has been going before the 2 new chickens were introduced and before they were allowed outside. I fed some cooked oatmeal this morning, but don't know if this is something serious or normal. I would say that is is happening on a frequent basis. Any suggestions?
