Leopard frog, caught in net that covers the koi pond in fall. Seems both back knees are dislocated or broken. No open sores or cuts. Have her in a 20 gal long with dry and wet side for a few days. Live in Indiana so bloody cold out right now. Has eaten some frozen brine shrimp and blood worms. Don't think we have any amphibian vets around. Help? Advice?
