So far great! I think I messed up. Had gotten a new rooster, little calico frizzled bantam guy, about 2 weeks ago, he's about 2 months old... but didn't have any issues or concerns, know should wait about 2 weeks to add, but don't think he's quite ready to go outside.... so added chicks to brooder with him after over 24 hours of drying in incubator, however never saw any bloody poop until the last little one got added, really glad I went ahead and started the Corid and fingers crossed all will be good, haven't seen bloody poop since yesterday afternoon, and hoping for the best. Still kinda new, only have had chickens about 2 years and first time gotten an older chicken through the mail. Feel kinda dumb now and could've lost 4 babies, but again fingers crossed and 1,000 times learned my lesson
