I've been seeing a lot lately about Avian Osteoporosis and it's frequency among Brabanters in American flocks. What are all your thoughts on this? Does anyone have a AO-free flock?? I heard that all the affected birds come from Ideal stock, even as far as 12 years back, but obviously I don't know that to be the truth. Does anyone know if Show Me Silkie's, Rainbow Gate or H and H Poultry's Brabanter flocks comes originally from Ideal (not saying they have AO AT ALL, just wondering), as I am looking for a AO-free flock...
