I'm 'almost' a vegetarian but have the occasional Mt Barker free range roast chook, that's it. I think i'm paying for it currently with a vitamin B12 deficiency but can fix that. I'm hopeless with animals and my chooks will hopefully die of old age ailments.
So I might end up with 30 but still only a few eggs a day? More of an old chooks nursing home.
