Thanks Beth, would be great to have some comparison.
The GG boy (on the bottle) gets 4 x 450ml a day, plus some concentrates, Alfa A and of course has hay and grass/clover for about an hour outside. It is quite complicated at the moment, as I cannot leave Lilly the GG X AN out off the lead, as she jumps. So I take her (and everybody else) out for about 30 - 45 minutes late morning, and then bring the kids and her back in, as I htink it wouldn't be fair on her to be in on her own... We will try and put another set of (electric) wire on top of the fence and over the gates (as these are even worse for her jumping, she can put her feet up for some leverage!), but will need to clip the sheep first and also maybe get hay sorted...
By the way, I had to get the BT kids back to the vets for a second go at disbudding, both had new horn growth... Not too happy about it, but I gather its quite common. so we are back to kids with blue spots on their heads, but they can't butt each other, as it hurts!
