I posted earlier about one, and then the second. I now have a third doing it and wondering if it is something they carried in shell? They are all from stock I had shipped in (eggs) but all of mine are healthy and fine. Is there something that can be hiding out with the hatchlings? Symptoms, lethargic sitting still, then flipping head back/out/twisted flipping them on to their back, wings going at strange angle. If someone is holding them after they flip their head they seem to have to leap or jump, like they are choking. They are 5 days old, New Hampshire Red Bantams, completely fine until this morning.
