One of my 3 mo. old BR poults, seems to have injured her leg. I've checked the leg up and down and there's no heat or swelling, nothing looks out of place, however, she's not willing to bear any weight on it. I have her secluded in a large crate in the pet with the other poults. She's eating and drinking and otherwise looking bright and alert. I put some aspirin water in her crate. Hoping she just tweaked it a bit jumping down from one of the roosts. She's the "runt" of the poults, very dainty, and I'm pretty sure she's a she. Any thoughts? What could I be missing? Thanks.
