If you keep a good number of Jill’s I would definitely recommend a snipped hob, they save all the hassle of getting the Jill’s brought out of season every spring, and any unnecessary bred kits,
I keep my vasectomised hob in with the Jill’s all year round, he doesn’t bother them that much to be honest, when he’s done a cage full I move him down into the next cage, where as hobs that are housed separately seem more manic if that makes sence
I had a team of 4 jills out, the other lads had mixed teams of hobs and jills, I find the hobs are abit overkill for this earlie in the season, Il use my jills til about November/December then switch to a team af 3 hobs
