Try cutting his temp & see too. Maybe to hot?
If its a true hybrid…milk…you maybe keeping to hot …with not enough humidity. But any hybrid will be alittle touch & go temp/ humidity care wise. Try things till he stops…start with cutting temps…increasing humidity. Try recleaning the cage if its used.
