I usually wait till after 24 hours after I fed them their first meal. I just picked up a desert enchi yesterday. She is due to eat fri so ill wait till Saturday or Sunday to handle her if she eats.

No you don't need to breed them.

Just make sure who ever is sexing the snake knows what they are doing. I have read its possible to cause injury if not done properly.

All of our younger snakes under 500 grams are on a 5 day feeding schedule.
