Started striking

Help i have had my big corn snake for over a year i got him at 6 months old.and i have never had any problem with him hes a sweetheart and very tame. I since added to my collection and got 2 siblings from a clutch being sold by a friend. All 3 of my snakes are housed individually and are all healthy and handled regularly. But recently my new boy has started striking at me i never had this problem with my first snake or my new boys sibling. Is there a reason hes doing this or is it down to something I've done?? Please help???

What has changed? Have temps changed, mouse supplier, water quality, light cycle, handling frequency, new hide, new substrate. Any of those factors can make a snake aggressive, especially too warm temps - so start by making sure that is okay.

Everything is the same as it has always been. Temp is fine same hide same supplier of mice, fresh water twice daily. He should be due to shed but not had the usual signs could this be whats wrong?
