My 7 month old buck doesn't seem too excited to mount my females. This could be that they aren't in season yet, but I had one in there for over a month, and not once did I see them mate together... I just put another female in the pen, their tails twitched, and they "fought", he seemed to "expose" himself, but didn't try mounting... Are goats known to be shy? How would I increase my buck's "eagerness"? We're really hoping to see him prove himself as he's our only buck at the moment.
