Can you feed chick starter feed to older chickens?

[babychickens321]

My hen has been broody and the chicks are due around Sunday/Monday/Tuesday.
My question is that when I buy chick starter feed for them, can I feed it to my rooster and other hen as well? I did search up all flock feed but I didn't find one I liked - I buy my chicken feed from Allen and Page and would prefer to feed them something from there rather than a different brand.

^this is the feed I want to buy, but do I have to buy separate ones for my hens and rooster. Oyster shell will be provided.
Also, the nest for my broody hen is SMALL, there are three chicks but they definitely can't stay there. Can I move the chicks to the coop soon after all three have hatched or no?

there were older chickens on the cover of the feed as well as chicks so I thought it would be fine to feed them it

The main difference in the calcium intake. You ate perfectly fine to feed chick started to a flock, but their egg shells will soften over time (a month or two.)

thanks a lot. will the oyster shells not help?

Chick feed usually has higher protein too to aid in growth and development, I try to continue to use the starter feed until they are at point of lay. The extra protein is not needed in older birds but will not hurt them unless they are already overweight or something. Older hens need extra calcium.
