That being said I'll put some of my old loft photos here for example purposes.
Hopefully others do also so we can share some tips and best practices.
This first set is rather old and the photos are dark but it'll give some idea.
Right side of this coop is for the main breeders and the left side actually is two halves and for fliers.
The middle bottom is for supplies and the top section is for injured birds and can be used for pairing purposes.
The bottom gate is hinged for cleaning purposes.
Between this section and the coop is the half inch galvanized steel flooring.
The roof slanted forward so it is easier to control the young birds that land there but disadvantage of this vs. the back slant is during the rainy days you get rain poured on you.
I guess a small gutter system would have solved that issue.
Small supply cabinet at the bottom section of the middle.
Middle top section is two halves and can be used for pairing birds or to keep injured birds.
Inside of the breeder coop. Box shelves are designed so the waterer fits under them in a way the birds can't perch on it and it does not get soiled from the boxes above.
Nest boxes are split in half to provide space for the following set of eggs to prevent the birds getting on a search of new nesting location and cause damage to other babies or eggs.
The few extra perches on the walls are there to provide space for males who have a habit of not staying in the box when the hen is sitting, to prevent fights.
Nest box bottoms are made to slide out of the shelf to make the cleaning easy.
Floor set up.
