These days chickens are fed special food which contains waste of animals… May be halaal or haraam. The poultry feed ingredients mentions animal proteins and no mention which animals or whether it is halaal. 1 can we eat these chickens? 2, if these are fed clean food for three days do these chickens become paak to eat?

Once once the chickens are fed clean and lawful good for three days, they become halal for you to eat. Nothing to worry about
