I believe my Southdowns would be similar in temperament to Ryelands, and my Badger Face possibly similar to Icelandics. All have been raised as one flock for six generations but there are still differences. The Down sheep get fat on fresh air, whilst the BF's eat 40% more hay than the Down ewes when in the shed pre-lambing. The Down sheep are very docile whereas the BF's start to go stir-crazy if in the shed for more than a week and like to move fields every ten days. We put our BF's to the Down rams every three or four years, to give a commercial type cross that sells well as store lambs
