Ask. They might be happy to tell you since it doesn't smack of a trade secret.If you have a goal age to put into the freezer, would that weight at that age be the most helpful?? Just because a bird fills out heavier than another at a later date, how is that helpful?
I noticed my boys start running the girls-- I would think they should be culled by then or put into bachleor pens out of sight of the girls, to finish the selection as breeder stock.
I haven't figured out how to free range girls and boys separately. WOnder how YHF does it??
