Thanks TropBeaucoup, I will see if I can try a bag of the pea formula to see if they like it better. I think a lot of the powder in the feed is the flax meal. I can't imagine they would have a slower growth than they currently are, seeing as they are just plain not eating those all important amino acids. I guess this is where all the other goodies they get help to fill the gap.
I think we might have chatted before about Skara Brae. On that - she has gone MIA for me now too. She mentioned having a lot of things to juggle. I really hope though that she is able to get back at the business come early spring. She has all the breeds I want!
