When to let chicks out daily?

[Nate Caskey]

I have 19 seven week old chicks that are too big to be kept in there grow out coop all day long, they have an attached, fully covered, run but I live in Kansas City, Missouri. Our average high is in the mid 50's. Is this too cold to start letting them out daily?

I would let them out. They should be mostly feathered and weaned off any extra heat by now.
