I had chickens for 9 years so I've had my fair share of emergencies to deal with. I'm kind of stumped on this one though I have some of my chicks that I hatched from my flock of birds and then silkies in with them that hatched around the same time they came from a breeder. They are the only ones in the brooder that are lethargic and their wings are drooping. I already thought of coccidia so I put Corid in their waters and I put save a chick in their water as well. They're eating a little bit. Ppop is watery, no blood but what would cause just the Silkies to be showing signs of lethargy and illness when the rest of the birds are just fine? They are far more timid than the LF, could they have been bullied out of food?
