Who and When?
The natural illness free standard recommend that chicken to have access to pasture.
There are also provisions that allow temporary confinement due to weather, conditions that threaten the health, safety, and well-being of the animals, and/or the threat of negative impacts on soil, plant, or water quality.
General accepted animal management systems aside from the intake requirement, there are no restrictions on when the animals have to be on pasture. Therefore, it would be reasonable that during the hottest days of summer, the chicken could be kept in the pasture during the day and coop at night. This assumes, of course, that the coop provides a more comfortable environment for the chicken in the heat.

The issue of treated fence posts that are treated with prohibited materials are not allowed, but that treated fence posts already in use could be permitted to remain in use on the farm. The only exception to this standard would be in vast rangeland and semi-arid areas where alternatives are not available.
