I need advice. I'm new to chicken owning and we've been going along just great until today. Today our 7 month old lab puppy somehow got out into the yard with our free ranging chickens unbeknownst to us. He's been doing a lot better not chasing them when we are out with him, but normally we never let him out on his own while they are out. He attacked 2 chickens today, killing one, and injuring the other. The living one doesn't appear to have any puncture wounds, just a few missing feathers. She was not initially standing when we found her just laying there on her side. We put her back in the run with the other 3 chickens and now she's standing and moving. She was also able to walk from the coop to the other side of the yard after the attack.What else can we do to help her along? Any signs we should look for? I know for certain we'll be a lot more diligent about knowing where our dog is at all times. Thanks for any advice!
