If I were to add older hens?

If I rescued some hens would I have to get a seperate feeder Since my chicks are still on grower?

I wouldn't necessarily. You can offer oyster shell, free choice. Grower has a little more protein, and doesn't have the extra calcium. Layer hens can eat the extra protein feed, and when you offer them oyster shell (at the height of their backs so the little chicks can't get into it), they should be able to get enough calcium to keep their shells hard.

OTH, integrating chicks with older hens COULD be a problem - with the chicks getting torn up by the older hens. I wouldn't integrate them until they've grown nearly as big in size as the hens.
