Black Rocks Space

Hi,

I have been busy making a new chicken house..

I have the nest box's about 12 inches wide and deep, by 10" to 14" high
(sloping.)

I have 4 boxes in there.

I am looking to get some Black Rocks as I hear they are the most productive
and hardy breed.

So how many is it per nest box?

I should have lots of perch space about 10 feet in total, across two
perches.

Thanks,
Mark.
