I can’t tell actual height from the photo but those look reasonable height. I don’t see any food or water in there so they should have room to get up to both the nest and roosts and back down. I don’t know why the nests are so bright but with that board across the front to keep the bedding in they should be able to perch there to get in the nests.
They are bright in the picture because I have the door open. We can collect eggs from the outside.
What kind of chickens do you have? Are they Silkies or some others that can’t fly? Do they have so many feathers covering their heads that they can’t see? A normal chicken should have no trouble getting up there but certain exotics might have problems.
Well I'm not sure. I bought them at southern states and was supposed to have 2 leghorns, maran, and I got one mix from a friend(not sure about her either) but they are regular size chickens.
How late did you put them in there and how dark was it? Could they see to get to the roost?
It was dusk so I could see pretty good but I'm not sure how well chickens can see.
Were they roosting before you put them in there? By six months they should be roosting but part of it is a learned behavior. If roosts were not available when their instincts kicked in for them to start roosting they may have bypassed those instincts and learned to not roost. Aart’s suggestion to put some up there after dark might help break them of that habit. Once one starts to roost the rest usually follow pretty quickly. Usually, not always.
