I had a predator attack my flock. Lost 5 of 15. I lost 3 of 4 - 4 month old chicks. The last sizzle roo is so traumatized (but not injured) that he sleeps all the time (deep heavy breathing) and doesn't come out to eat or drink. I brought him in the house into a crate because he no longer has his 3 crew members to hang out with. They had only been integrated a few weeks before the attack. I pray he comes around but when he does, I'm concerned about re-introducing him. Any suggestions on how to help this baby?
