If you are going to breed it is necessary unless this is going to be your only litter and you are prepared to keep all the bucks you don't get homes for.It is impossible to keep finding good homes for bucks.Don't waste any time fretting over it,if you are going to breed more cull all the bucks now and enjoy the rest.It can help if you can find someone who has an animal that eats pinkies,circle of life,instead of wasting them.None of my pinkies are wasted.
