How do you know they were in breeding, 1.5's bucks breeding there mothers is very unlikely considering the first thing the mother does is run them off. And as far as there being too many does it is likely then that there was a bunch of big old angry matriarchs that like to run off the 1.5 and 2.5 yr old bucks. And also when there is inbreedding you would think the racks would be pretty inferior like basket racks and such, not big like your saying.
I'm confused after reading this. Try re-reading the post and you may answer your own questions. As far as the 1.5's breeding their mothers...how do you know they aren't? When nature calls what do you expect to happen.
