It looks like a chicken palace, both of these shed conversions. Having a storage area makes a lot of sense, and you can open the main doors without the chickens getting out and to allow air and sunshine to get in.
MadabtChickens, if that is the height your nesting boxes will be at, you might want to add one more nesting box low to the ground if you plan to have any Silkies, as you mentioned.
Also, it appears the nesting boxes are sitting on a workbench or something. The chickens will stand on top of the boxes and in front of the boxes and poop there. Can you mount the nesting boxes to the wall? You can put a board at an angle on top of the nesting boxes so the chickens won't stand there. You can also just mount a pole in front of the nesting boxes to allow the chickens to hop up there, but there won't be a flat surface for the chickens to poop on.

It will be easier to clean this way.
It's looking good.
