I have heard of some small girls breeding but I mean 1100 grams on the low end. 850 grams in my opinion is ridiculous. Even if you can get them to lay for you at that low of a weight they will most likely slug out the next season and most likely many more after that. This is a perfect example of someone wanting to rush things and put the snakes health in jeopardy. IMHO I think you are exactly right and he has lost it for lack of a better way to say it
