I frequent the Pet Trades and NEVER see a Cockatrice that is homozygous for Bet Expert. The ones I've seen are either carriers or don't have it at all. I've also noticed Bet Expert is asked for in Quests enough that I wonder what a homozygous Bet Expert would go for in trades regardless of GP or color. Anyone?

If I buy a pet for a quest, I’m usually willing to pay as much as the quest is worth so I at least know I get my silver back once. But that’s just me, I don’t know if anyone else does that.
