I keep my hobs together when they are not breeding and out of season. I also let the jills and babies after the age of 6 weeks play with their fathers. You need to check the area you live in to see if it is legal to breed some states you need to be licensed and some are illegal to breed. You need to have a good vet cause if something can go wrong it will. Jills died for no reason and you need to have a foster mom to care for her babies. Jill come in to heat and hob are out of season. You need to be willing to put new born babies to sleep when there is no foster to care for them. Can you do that. Can you watch you Jill died because you were the one that wanted her to have babies and she died because of it. Please really think it over and check everything out before you try breeding ferrets. Also you better have a good job it will cost you more to breed and care for the babies then to go to a pet store and buy babies!! [Posted in FML issue 4155]
