How to feed 5-6 week old chicks along with older hens?

[Swampchicken1]

Recently bought 6 Rhode Island reds to add to my flock of 17. Wondering how I will feed them alongside 1 yr. old hens? Brooder is 2.5’x3’ so I don’t think I’ll be able to keep them in that much beyond 5-6 weeks. How can I feed them alongside my (17) 1yr. old hens without having to separate them. Plan to put brooder in run to introduce them for a few days but what do I do after that? Thanks

Chick feed or All Flock is fine for the whole flock if you offer oyster shell on the side for the layers. The chicks won't bother with it until they need it.
