We hatched out five baby chicks three days ago, the eggs were from a farm swap. One died within less than 24 hours, and seemed weak from hatch. One was fine, but this morning woke up weak and lethargic. I brought the chick in (they are with a broody), and started electrolyte solution. The baby had two bloody poops, so I started him plus all of the other chicks on corid in the water for cocci. My question is, can they develop cocci this quickly? They have been outside since day one, but I read that the incubation period was 5 days, and this one was sick after two. Could this just be weak chicks from poor parent stock? I don't think there is much hope for this chick, he isnt' even peeping anymore, and now he won't stand up, just lies on his side. I have been able to get the corid plus some poultry drench and mashed up food into him, but he is going downhill fast. The other three seem fine, out with mom in the run, being chickens. Any help is appreciated! If there is anything else I need to be doing for the sick one or the others, please let me know!
