I need some advice. I have 9 chickens in an 8x4 coop. Every day I go out to the coop they have made a huge mess of the pine shavings. Everyday, I level it back out again. I go back in the next day and there are areas that they have completely scratched down to the dirt floor and then other areas that have 2 feet of shavings! I don't get it? Is this normal? I am a new chicken mom, just since May, so I've never experience this before. I try to keep it looking fairly decent out there, but everyday they make a mess. Thank you in advance for your comments/advice!
