I'm new to raising chickens and have had a couple of close calls with two of our three so far. We have two Ameraucanas and one Buff Orpington. One Americaunas appeared sick and lethargic two weeks ago, but after probiotics and electrolytes seems fine( phew!!) Today, They were out free ranging in our backyard this afternoon, under our supervision. After my older daughter brought them back into the run I noticed the little BO standing on one leg. Upon closer inspection I see the bottom of her foot is pretty swollen (no visible blister, bee sting, etc.). The leg and foot are also a bit swollen and bruised. I can't even imagine how this happened so quickly. Now I'm thinking she broke her leg? She's still trying to stand and is a bit shaky when I pick her up. She's vocal, but always has been, so I'm not sure if it's related to the injury. I tried an Epsom salt soak and also applied a baking soda paste to her foot in case it was a sting (which doesn't explain the bruising). If her leg is broken do I just leave her or can a vet do anything?
