This will probably muddy the water some, but here is a point not mentioned in the previous posts. In a lecture given by Attorney Mike Oropollo, at a national convention, the issue of possession limits came up. Many of the observations made above were voiced and discussed - in the end, Mike's opinion was that a bird (any bird legally taken) that enters your shop and is properly recorded, ceases to be owned by the individual and becomes "owned" by the shop - not the proprietor of the shop. Thus, you could have 500 birds in your freezers and not be over "your" limit. The point he was making was that if you enter your personal birds into the shop record with all the relevant requirements, "your" bird changes custody to that of the "shop". In effect, this is what your customers are doing and the option is apparently there for you as well.
