In the summer heat, locking them in a coop for 3 days just might be a death sentence. I would set them up with a run attached to the coop. Even if they are ALWAYS free ranged, there are times IMO when it's just prudent to have the option of using a run:
Predator comes calling.
Training new birds to coop OR NEST.
You have a broody and chicks, and know that letting such little nuggets out to free range would be a death sentence for them.
