HELLO! I read through and tried to gather the info I could out of here..... but one of 8 chicks I have together right now started laying bloody poop yesterday, im not sure which chick it is so how do I go about treating it ?? im also confused ive read multiple different things on here ..... the chicks are 4 weeks old, been healthy since the get go, everyone appears to eat and drink normal. but started noticing yesterday a few blood poop piles and more this morning. most answers talk about Corid ?
