I just built a new coop that is 8x8. I have 13 pullets. 5 of them are about 8-9 months and the other 8 are a little over 4 months old. Since they have "moved in" to the new coop they seem to pile on top of each other at night on top of the roosting boxes or inside of them. It seems that 10 will be together and maybe 3 of them in different areas of the coop. The problem is they are using the bathroom in the nesting box that they all use making it a mess and of course the eggs are messy too. I have 4 nesting boxes with ladders going up to them and a 4' perch but they never use that. Am I doing something wrong ir is it just the way it is? Any siggestions would be appreicated.
