Questions from a newbie

[Agsgranik]

I have a couple of questions I’m hoping y’all can help me with.
Firstly, one of our hens was laying regularly since we got her, but has not layed in the past 4-5 days. Also, her comb is floppy. Otherwise she is behaving normally; eating, drinking, free ranging with the flock.
the other question is about their coop and the fact that at least three of the five chickens don’t Roost on the bars, but sleep on the shelf above the nesting boxes. Should I worry about it or just leave them alone?
I’m attaching photos of the coop and of Louise.

A floppy comb is normal and characteristic of many breeds. Hens often go on egg strike, just keep an eye on that. Chickens roost wherever they want to roost, this is normal and little can stop them.

If that stick I can just see in front of the window is the roost it's both small in diameter and low.

Adult chickens need a fairly substantial roost -- the flat side of a 2"x4" or a branch of equivalent thickness -- and they prefer to roost as high as possible.

I agree roost is a little low and thin, and the top of the nest boxes looks really nice for sleeping on. Why is there a ramp up to the top of the nests? I'd axe the ramp and slope the top of the nests 45 degrees so any bird that tries to perch just slides off.
