Ahhh...yes, sometimes they race around freaking out, crashing into things and I just cringe.Their coop is about 2.5 feet off the ground, and if she decided to bypass the ramp to get out, she may have just landed awkwardly. I'm sure gimping around on it for a week didn't help things.
My roo was limping heavily a couple weeks ago, who knows what he did...kept a close eye on him and luckily it got better after a week or so.
