Miaowzen, My chickens all happily roost on metal poles. I have no wood at all. We had a HUGE mite infestation last summer where the red mite parasite things lived in the wood perches and all in the wooden house. So now their house is an old tank. After that whole experience i don't think I'd be able to have wood in their house again


I do use sheets of thin wood,that we take down from the walls inside our house as we renovate, these are used at the bottom of the tank as a lining/floor - then straw on top, but as soon as the wood becomes soiled, it's replaced...(we have plenty of it

) very easy to clean .. because i just rake and change the straw every few days and then chuck the whole lot wood and all on a bonfire each week or so when it gets too yucky.
I'll try to take a pic of how our night house is, ANYWAY.. i have rambled on enough

I'm just trying to say diff things work for various reasons, and there may not be one hard and fast rule

your house looks very comfy, I'd give it a bit longer and see if they settle better in time.
