The wire you see on the wall in front of one of the older chick swings down and can be locked in place to keep air flowing but the new chicks in and big critters out. The floor is cleaned and I put down about an inch of wood chips for the baby chicks. It doesn’t cover the floor but will dry up any droppings and not ruin the wood floor. I have used this type of bedding for almost 4 years. Works great, change it out 2 times a year. If you throw mealworms in 2 or 3 times a week they will keep it stirred up and dry. You can see it’s not very thick, but they will bunch it and make a nest. Back to finishing the coop still need to clean the windows………..
here is just some random pics.
