Nesting boxes too small?

[Donette]

We built a 4’w x 6’l x 4’h coop with 3 nesting boxes across the 4’ portion. With all the framing, the nesting boxes ended up around 11” wide, 12” deep, and 18” tall. Are these big enough for light Brahmas? I bought my birds after hubs built the coop but did not consider the nesting boxes.

They should be ok. That is really close to the size mine are and my brahmas haven't had trouble using them.
