Your dog will likely attack the birds again. The GAME is just to good not to play again... Don't let your dog near the birds again. This was a test run, next time he will kill them..
Glad to hear the roo is doing better. Mine took many weeks to return to normal attitude.
I just went through this. My rooster hid in the coop for the first few days after the attack. His comb was laying flat on the side of his head like a leghorn hens comb.
He slowly started coming out of the coop. He still didn't act right. He didn't mount the hens, didn't crow, wouldn't...
