Yesterday received chicks from breeder. Some were hatched 2 days ago and the one with the bloody stool looks older so I am going to say a week old. First can chicks get cocci that young? Second i know to get Corid but should I treat all, even the two day olds? The only other thing i noticed is her crop is a little full and hard. I am not happy with this breeder as one chick was dead on arrival and the others were very week. We got them warmed up and gave them sugar water, they are eating and drinking but sleep a lot. I thought they were getting better this morning and my other batch of chicks from a hatchery(all very healthy) arrived this morning. 30 minutes after putting them together the oldest chick from the breeder pooped bloody stool. I immediately moved the hatchery chicks to another brooder and gave the sick chick a drop of Kocci. Now should I get Corid and treat all? I am worried about how young they are.
