Lisa, you were asking about the leeks..and your hens eating them. Leeks are like onions..strong flavor that could alter the taste of the eggs they lay...maybe want to reconsider giving those to them...or if you want already flavored eggs...then by all means...people who also give flax seeds to their layers also report of a "taste" if given too many. They can eat them..in appropriate amounts if you don't want altered flavor.
