I was just wondering how early most bucks become interested in females. I have a buck who is a little over 4 months old and is not even remotely "bucky." The only thing he does is pee in his mouth on occasion. I have had him out with a couple of pregnant does so he learns some social skills. They were both very nice to him and never attempted to beat him up. I have had him out with an open doe for several weeks now. The new owner wants him to breed her. I told her there were no promises because of his young age, but felt it was good to leave him with her for social skills..considering the new owner wouldn't mind if he managed to get the job done. They tend to exist peacefully, although she does want to headbutt him at feeding time. The thing is, he has zero interest in her. I haven't seen her come into heat, but he doesn't even tease her or do bucky things. I've let him play with my two 3 1/2 month old doe kids (under supervision), just to see if he would act bucky with something less intimidatingly big compared to him. Nada. He can have his nose right in their girl parts and he doesn't react at all. The buck I used to have was ridiculous. He continued to sexually harass all the females even when they were preggo. He did the tongue wagging, pawing, snorting..everything. He was 10 months though... This new buck hasn't done a single one of those things. I have a buckling who is only a WEEK old and is already tongue wagging, pawing, snorting and mounting his twin sister. I guess my question is, when should I be worried about him being a dud? How old have some of your bucklings gotten before finally starting to act the part?
