I have 8 hens, 1 rooster and 2 rabbits that all share the space. The coop is about 4x8 and is elevated, has a mesh floor. The chickens and rabbits go in and out as they please, They have a 10x10 fenced area and can get under the coop if they want. Their 'yard' is all dirt and I will toss in grass and scraps for them to rummage through as well as laying pellets. They are almost 3 months old now, so still a bit away from laying, but there are 4 nesting boxes in the coop. What else do I need to be doing? Do I need to clean out my chicken pen, Everything falls through to the ground when they are roosting.
