No idea. It is just what I observed in real life with raising a flock of 300 sheep over the past 30 yrs. So, I had approximately 12 herd sires that I used on the ewes, but all the births were approximately 50/50 male/female and we raised the majority of the males for meat animals to anywhere from 6 - 11 mos of age (till they got market size, but less than 1 yrs old to still be considered 'lamb' and not sheep), and the majority of the females were sold as breeding stock, barring any defects or low performance numbers. Very few males made the cut to be sold as breeding stock.
Ultimately, I would suspect that it is caused by a high sex drive and lack of females to use it on. But there have been males that people have had to ship because they preferred each other rather than the females, when they would put 2 or 3 males in with a large group of females to breed.
Ten to 15% of males are homosexual...I wonder why that might be, from an evolutionary point of view.
