We ran some Charollais across our commercials (Texel types, originating from Swaley Mules and Hexham Blackie Mules predominantly) for three years and kept the ewe lambs we liked. They are super ewes for producing easy-lambing fast-maturing fat lambs, hitting the top grades. All the lambs with some Charollais in them weigh more than they look, so finish a couple of weeks (at least) faster than those without any Charollais.
We carefully chose Charollais tups with wool on their heads, and mostly the lambs are not too bare for our outdoor-lambing Cumbrian upland farm. We do jacket them if it's cold and wet weather is forecast.
Our best fat lambs from these ewes are sired by a Dutch Texel - a squatter sheep than the Texel, finer fleece, shorter legs. We find them to produce small active lambs that quickly grow into brick outhouses. These ewes do well put to a regular Texel too.
Lleyn produced too many multiple births for our farm.
