Best to start new threads instead of piggybacking off an old one, especially with this many questions not relevant to original topic.Ok, I'm not seeing any threads related to my questions
They won't. It sounds like you haven't been excluding them from the nests from the start so it's no different to them from any other part of the coop. Especially with them not roosting, any part of the floor is fair game for sleeping, which includes nest areas that probably just stick out to the side off the floor level.1. How will they know to stop pooping in the nest boxes once they start laying?
You might want to reconsider how you're managing poop. Litter is more absorbent and will last longer.I don't use bedding inside the house, I have a pet mat in there that is fuzzy like felt on one side and waterproof on the other.
Need to see the roost set up. Likely it's far too low to make them want to use it.There is one roost in there, but they don't know what to do with it.
I wouldn't put mats into them until you fix the problem of them sleeping in there, because: see #3.Now that they are almost laying age, I'm thinking of putting nest box excelsior mats in one the boxes to indicate this is for something else... and a nest egg.
1 per nest is fine.2. How many nest eggs should I put in?
AFAIK they're not meant to be cleaned. You'd toss them if they're soiled.3. It seems like those excelsior mats would be impossible to clean if they got even one night's poop on them.
You can, but they must have access to it at sunrise. If you're going that route I'd consider scrapping the idea of using the nests in the coop at all.4. I'm thinking of putting the little pet crate nest box in the bigger run in a secluded place.
Yes, usually. Sometimes young layers will lay off the roost at night but that's due to lack of control, not because they want to lay at night.5. Do they always lay in the daytime?
