I have a 1 month Mallard with an injured R leg. I noticed him limping and not choosing to use the leg, however still has mobility of it. Upon eval it appears his R knee is swollen (compared to the L). He is still moving around the pen with the two other ducks but with some difficulty. I don't know if placing him in a cage would help, so he doesn't move around on it and give the leg some rest, however would the stress on him not being with his buddies be bad? Or should I just let him do his own thing and be happy he's with his buddies? Right now he's in a small cage in side the pen so he won't move around but can still see everyone. Am I doing the right thing? Comment, questions, or concerns? Thanks!
