I have four black jersey giants that I got in April. Two of them are as tall as my rrs and borp and two of them are even taller. I lost one of my borp a few weeks ago so I had to get a rr,amerc, two b rocks and two more buffs. Now I need my transition pen for the new babies, is it to soon to put the jg with the ladies? They roam together in the back yard but the ladies still pick on them sometimes. If I do what would be the best way?
