Oh interesting. I don't know. In their video they say both 'one of the farms' and 'one of our barns' - so maybe it is both.I don't think McMuray has breeder birds. Don't they just buy hatching eggs from nearby farms? Could be wrong but I know some of the big hatcheries buy from Amish farms so I assumed they did it the same way.
Again on the video they definitely explain that they are not delivering eggs/chicks to customers in order to preserve them to restock the breeder stock - but I guess that could mean restock the farms, I just took it to mean that they had breeder stock themselves, but I may well be wrong.
