Worn out breeders "normally" make crappy pets unless you treated them like pets when they were breeding.
My breeders are handled almost daily, never bite, and have no issues with me handling babies or them whenever I like.

Advertising them for food for larger snakes is a better bet for older breeding stock.

I gas them and freeze them and then when I get a group large enough I advertise them as jumbo frozen feeders, they always go fast
