I’ve heard that raising the hybrid layer/meat birds for a season usually ends up slightly to significantly over the cost of premium eggs and chicken. Exact amounts vary widely depending on accounting etc.

There is a point to having both - or at least giving an idea of how much an item typically weighs. One cookie might be 200g or 50g; people may typically reach for 1-5 cookies, for example.

A misleading serving size (eg “per 1/4 cookie”) is indeed not helpful at all, but I don’t think it’s illegal.

Beef, almost completely.
