Did you mean to put this on "treats for taming"? Cos it seems not to follow on for me - and teaching tups to expect hand-fed treats is very much *not* recommended!
Mixing tups...
1. Do not mix horned and polled. Full stop, period. Just don't do it. (Somebody will tell you how to do it I expect but I was told this, then our Swale jumped a wall to get with the BFLs, and one of our best BFLs lay dead within minutes. So now I pass on the advice and the cautionary tale to go with it.)
2. Pen the tups tightly together so they've very little room to move, can't get a run up so can't really damage each other. *Let them get used to each others smell for half an hour to an hour, then give them a little bit more space (and keep watch to be sure nothing is kicking off.) Repeat from * until confident they can go out together.
Yikes, re your tup!
My 2, Triplet (Dorset Down) and Cyril (Bleu Du Maine) lived quite happily with BiL's Thomas (Lleyn). All come to bucket, never fought, even jumped a wall at my dad's to get to his lawn, (well, Cyril & Tom did, Triplet was too fat and too short so dad opened the gate to let him mix with the others, only to yell at him when Triplet charged for his reflection in the French Window!)
BiL sheared them there, one after the other. STILL to this day I can hear my dad telling me to get between them as without their fleeces they looked different to each other and were charging one another! Told him he was bloody stupid, think BiL said something a bit more polite!
They calmed down but it really made me think. (During 2001 actually had to use a cattle prodder on a Texel tup as I couldn't get away from him, I phoned for mum who came to my assistance, I was in middle of field and holding him away from me as much as I could. A few sharp shocks and he backed off. Contacted vet and he made a few phone calls as it was in middle of foot & mouth saga! New owners turned up and took him immediately as we asked vet to come out and shoot!)
My 2 tups were friendly, I reared Triplet and consider myself lucky with his temperament but am aware some .........yikes! Even the ones I've borrowed over the years, the temperaments have been excellent though BiL didn't bother like me "I can handle anything etc etc" He replaced his Tups every few years Thomas was the nicest! One tup he had, BiL "I can handle anything" found himself bowled over as the tup had decided he didn't like him in the same field and had charged him. Get rid? No, as that would mean getting another tup in (spending more money) so he told his kids DON'T go in the fields!
