So is that what's going on with Les? And now you're distracting me with seven beautiful eggs from Lu?
Haha. Just kidding. So far so good, right Bruce?
Personally speaking, I've done two breeder loans so far. One was with a gecko and went fine. The other is currently ongoing with two ball pythons. No problems with either. But we also had/have contracts that both parties had significant input on and that were signed.
I would never personally do it with someone I wasn't very trusting of or not friends with. And even then I think a good, detailed breeding loan contract is needed to fend off any possible issues. I think we've all seen one or two longtime hobby friendships crash and burn because the parties involved thought they didn't need to set out in writing what was transpiring... It can get really ugly.
