I've never seen a Hindu running a meat shop in my life, literally all meat shops in India are run by muslims, even the ones inside some superstores. Yet most of hindus are non-vegetarian, they want to eat it but not butcher it.
Seen plenty in East, North East and South too. Plenty in Maharashtra as well.
Good number of Hindu's buy mutton from non-muslim adivasi/local lads in Jamshedpur.
Lot of villages/rural areas don't have any Muslims for miles.. yet villagers are voracious meat eaters. If not chicken or mutton, there's fish or eggs in a meal at least. Culling, cleaning, chopping is done by Hindus onlee.
Don't write them all off as 'dalits'. The word was chosen by Jyotiba Phule and was seldom associated with lower castes. Same has been used to the hilt by vested groups.
