I'm currently raising a mix of chicks, mostly inside in brooders, but my bantam hen went broody at the same time as I started incubating a new batch, so I let her keep her eggs, a mix of her own and australorp x. Yesterday I went out to check on her and her now 3 week old chicks. There was an australorp x lying on its side, bleeding from both ears. I freaked out, scooped up the chick and rushed it inside. I quarantined it in a small brooder of its own, turned the heat mat up a little and monitored it closely. It seemed to be breathing very shallowly. By evening it was able to lift its head up and look around. Now come morning it's cheeping loudly and marching around the brooder looking for friends. I can't see any blood at all. I wonder if it was pecked hard by its mum and it really rattled its brains? Should I be worried about sickness? Should I continue the quarantine? It isn't happy being on its own. Thanks for any advice.
