Two days ago I noticed one of my beautiful 9-month old BOs limping. Brought her inside and discovered one of those darn hard plastic leg bands dug deeply into the back of her leg. When I removed it a lot of clearish liquid came out which I assume was pus. I cleaned with lots of saline solution and applied triple antibiotic then kept her in overnight. Yesterday I cleaned it again and applied triple antibiotic then returned her to the rest of the flock. Today there is a large scab covering the deepest part of the injury and she is still limping. I'm concerned she might get an infection so am wondering if it would be wise to get an antibiotic for her. If so, what is the best antibiotic for something like this? Thank you.
