When I have smaller colonies and/or nucs, I have never seen them allow a queen to lay large areas of drone brood, until that colonies population had grown quite strong. The only time I've ever seen this happen was with laying workers and drone laying queens, and those hives have much bigger problems than just too much drone brood.

Many foundationless combs have mixed drone/worker cells in patches across entire combs - in situations like those mentioned above the bees keep the drone cells in use as storage or even idle, while the worker cells around them get used, until the population has grown, then they will begin to use some of the drone cells to raise drones in.
