3 month Buck Fawn with limp

I know this may be hard to pin point but looking for some advice. In 5 years never had this happen and I know most of you have probably seen this.


Today I walked down to the fawn pens and my 3 month old buck fawn has a bad limp. Front left leg. He would put pressure on it when he walked. I haven't seen any wounds on it. He got up and limped about a 100 feet then laid back down. He is laying on that leg. His ears are lowered I'm guessing from pain. Doesn't look broke at all but before I dart him and figure it out of like to get some opinions. I have not seen any lacerations or swelling. I appreciate it

Pain full to lay down and when standing no pressure on leg. When walking very little pressure

Thanks. Appreciate it

If it's a thorn it should work it self out?

Handling facility is not up yet. I'll give him some banamine. No trees. Open fields. 1/4 of the pen I leave hi all summer. Did now most of it and it could have been from the thicker stalks of the weeds/bushes. Thanks again
