unless corns don't eat after shedding I don't see why he wouldn't be eatingI saw your other post. It showed the shed skin from your snake. Some snakes will not eat when they are getting ready to shed.
In 3-4 days offer your snake a pink mouse again. This time leave him in his feeding container alone with the pink for several hours. Make sure the lid is secure so he can't get out. Maybe put the feeding container into his viv if it will fit. Then leave him alone for a while. No peeking.
Hope this helps! Keep us updated.
Now thats a familiar face!How long have you had your hatchling for? If you've only had him a couple days, you should give him a week or so to settle in. Meaning no handling and just change the water. You don't want to stress him in his new environment, do you?
