Their on a special feed called Afriwing, along with their normal Alzu. They get molasis (sp?) blocks in their fields, and lots of hay and/or grass. Thank gosh its winter now, the grass is growing nicely :)
Free choice hay is going to be your best bet (and make sure that it is a good quality) ... is the special feed that they get a grain(sweet feed) or a pelleted feed?
I don't really know hw to describe it. Its kind of like a powder, with bits of both grain and pellets in it. I know that might sound abit odd, but the vet assured me its fine for them. The hay they have is great, its really good quality
