It really does matter. Breeding is alot of stress on bucks and when there is alot of does those bucks breed for a long time and dont eat much. Then here in the north winter kicks in and snow can become a problem for those bucks to eat. Anotehr note is that one of the pens near by had a breeder buck get into a pen with alot of does and no other bucks by accident, dont know hte whole story but that buck went from a 180 inches to 145-50 the next year and he was not goin down hill age wise. They said it really messed that buck up. WCL
