Mcgro, never turn your back on your tiny ram, they pack a whale of a punch! As said don't try to make a pet of him (if an entire ram) and don't let small children in the paddock with him! The best thing to do if he does try to have a pop is to put a bucket gently over his head or take him (again firmly but gently) by the horns and tip him up.
Kanisha, All I know about Ouessants is from the little flock I had, not for long enough, sadly but, as to colouring, I had 4 white ewes and a black ram and he threw white ewe lambs always. would this be usual?
