Found one of our 9 month old roosters in a nesting box yesterday almost comatose. head droppy, eyes closed - didn't resist when we brought him to the house. Had a big clump of poop on him which we removed. Gave him Terramycin in water by dropperful and at few points he opened his eyes and looked around then back to head on the bottom of the crate. Removed him from the rest of the birds in case they caught it too. Not sure what it is? Does anyone have any ideas? We also had some other antibiotics which we gave him today twice but no improvement. Its as if he is sleeping with eyes closed, head flat on floor - not even curled into sitting position.
