Hi,

Is it possible you are offering or pre-scenting in a different way to the breeder?

It might be worth asking him to run through his feeding and food prep routine with you one more time to see if anything jumps out.

Also what is the actual cold end temp - if he was heating the room to a higher level that might be enough of a difference.

Are you handling them more than the breeder was?

It might also be worth trying the substrate change if nothing else makes sense.
