I'm sorry that Penny broke her beak! I have a soft spot for barred rocks.
Kua healed in a little less than a month, but I was lucky to have a good vet and we were on top of the injury within two hours of it happening. Luckily, the soft tissue inside the beak that causes growth was not damaged beyond repair and her beak grew back quickly. She was on medication, good food, and she is only a few months old so I think they all helped her to heal quickly too. I had her in the house for weeks and she was a bit spoiled during that time.. She was a sweetie!
