When some pullets start laying they have complete control of the process. They know where they want to lay and recognize the signs of the egg coming, so they go to the nest and lay. Others don't have control of that process. They have not selected a nest and do not recognize that an egg is coming. They drop it wherever they happen to be, whether on the roost or just walking around. If you consistently find eggs in the same spot they have decided that is their nest.
The egg laying process is pretty complicated. It can take a pullet a few days or even a couple of weeks to get everything straightened out. That includes putting the egg together correctly as well as when and where to lay the egg. To me, it is surprising how many get the whole process correct to start with.
Some people really care how high a nest is, whether their preference is on the coop floor or higher on the wall. From what I've seen chickens don't care that much. If you have a Silkie or another chicken that can't fly height might matter but that pullet can easily get up there if she wants to.
So what can you do? Put a fake egg in a couple of those nests. I use golf balls but you can get wooden or ceramic eggs at a craft store. Sometimes that is enough to get them to use the nest.
Keep any other eggs cleaned up unless they are in a nest. They often (but not always) like to lay where another egg is. That's why we use fake eggs.
I made a couple of my nests so I can lock a hen in them. If a hen has established a nest somewhere else I wait until I can catch her on that nest laying and lock her in a real nest until she lays. That often involves chasing with a fishing net. Most of the time they lay that egg within 30 minutes of being locked in there. Usually it only takes one time for them to switch to the real nest. They probably decide it is a safer place to lay there than where some maniac is going to be chasing them with a fishing net.
Another option is to accept that place as a nest if it is where you can handle that. Either just leave it alone or build a nest and set it over that spot. Some places are not going to be acceptable but some might be.
Also I was told she was a cinnamon queen on another post but she’s laying light blue eggs. Any idea what breed?
Where did you get her? Who called her a Cinnamon Queen?
If you got her from a hatchery, which hatchery? If you got her from a feed store, do you know which hatchery they got their chicks from? If it was from another person, I haven't a clue.
Cinnamon Queen is a marketing name, not a breed. They are a cross between different breeds and colors. Different hatcheries use different breeds/colors to make their Cinnamon Queens. Since she is laying a blue egg she is not a Cinnamon Queen from any of the possible crosses I'm aware of. If you want to call her a Cinnamon Queen you can. If you want to make up a name you can. The chicken police will not be around to arrest you. To me she is probably a mix of something but I don't know what.
I understand it can be important to some people to know breed, marketing name, or some other label, but to me either they work in my flock or they don't. Good luck!
