My light sussex was running around in the garden along with the rest of the chickens when it managed to jump out of the 5 ft pen without me noticing. I opened the back door to let my dog out (German shepard) and he found her and took a bite, he pulled out alot of feathers and had the wing in his mouth before i managed to get him to let go. Shes only just 24 weeks old and has just started laying. Shes got a tear out of her wing and its bleeding alot. I cleaned up some blood and she seems to be able to walk/flap eat and drink fine. What should I do? Shes crowing(i think...) like shes in pain. I don't want to put her down. HELP!
