My lab/ shepard mix got out while the chickens had been free-ranging - there were only 2 that hadn't made it back in the coop. He got the first one but I was there in a second, so I thought he only ruffled a few feathers- never saw any blood, just a lot of feathers. She seemed in shock so I moved water and food near her and put her in the shade in the coop run. End of the day, she wasn't moving but was breathing and appeared 'ok' so I moved her into the coop for the night. Today, moved her out and she hobbled along for just a few feet. But she is not eating or drinking today. I think her right leg is injured, she will walk on it but limps and mostly just sits. Is there anything I can do for her?
