I have 8 Black sex link chicks in a seperate coop, and I guess you could say they are at "teenage age" and I feed them Purinas medicated chick feed. In another coop I have one yard hen and she eats laying crumbles. Soon I will be introducing the sexlinks to the older hen as a permnate home, what is best to feed them all? Will feeding the sexlinks the laying crumbles hurt them when it comes time to introduce,since they are a bit younger than the one hen (at least not old enough to lay)? Or what is best to feed them all I should say? On a daily basis I lead the sexlinks to the other coop to spend time with the one hen & get use to each other and then lead the chicks back to their own coop. ( And they all seem to be getting a long fine...for now) My sexlinks I believe think that they are dogs because they love my attention and love to be handled or pet I've never raised chicks before,so I treat them like they are a pet- they have really grown on me and are now probably my favorite animal, because of all the diverse personalities each one has.
