Hair loss

Hey guys I need opinions!!!
I have a yearling buck who started losing small patches of hair on his sides, he routinely lays curled up in a ball. He will get up and eat/run/act normal when I bump him up. So yesterday I hit him win draxxin and another antibiotic. Woke up today and his antlers are off.!! I have no clue what's going on. Any help is appreciated!

Also, I need to put it out there, this buck did not even start shedding velvet until a month ago!!! And he only rubbed 10% off maybe. I do t know what's going on with this guy!

Ok thanks
