Hi Francis
At what age are you thinking of for GOS, at present the castrated males I have are approx 8 months old. They are used to being with what I call the creche, ie little ones.As i said in my PM there are some great experts on here, for example Pigsatlesrues and Hilarysmum to whom I always seek advice from, they will soon correct me if I am wrong here, but I see no reason why this mix should not work.These castrated males are very tame and used to humans and are not typical escapees!!!!!! unlike some I could mention but not here!!
Keep an open mind, speak to the OH and seek advice from others
Talk soon
