My coop has a wire floor with a pull out tray underneath to catch all the droppings. When my chickens dig around in the nest box, they are throwing shavings onto the wire floor, which then fall through and fill up the tray. When I try to pull out the tray to empty it out, I can't pull it out due to the excess shavings. My question is this: Should I go ahead and put shavings in top of the wire floor and not worry about pulling out the tray to clean it, thereby having the deep litter method? I am a little worried about my chickens being too cold without shavings on the floor of the coop. Also, my chickens are 7 months old and still have not layed any eggs. Could the problem with the wire floor be keeping them from laying? They are pooping in the nesting box, so I think I am doing something wrong, but not sure how to correct it. Thanks for any help you can give!
