I agree with Dtala, every deer I've had with a break in the leg they healed better on its own rather then me messing with it and a splint all the time. The first call I made to an old deer farmer with my problem and he told me to just leave it alone and it will probably be fine. I had one that broke his back leg as a month old fawn in between the knee and hip to the point the leg was flopping. I just let him alone and he stayed calm and it healed perfectly. After about a week I could tell it wasn't flopping and after a couple weeks he was starting to step on it about every third step and after a month he was using it about like normal. He is now one of my breeder bucks and shows no signs of being different from one side to the next as far as antler growth. Usually if they have an injury it will affect the rack on the opposite side. Deer are amazing at healing themselves. I had a wild young buck at my farm with double drop tines that only had one back leg, I was going to shoot him and put him down because I thought he was suffering. The day I found him he whooped a big bucks a$$ and bred his doe right in front of me. Needless to say, If he could still do that with 3 legs he deserved to be alive! He was around for several more years and then last winter he finally disappeared, coyotes probably finally got him down. good luck
