Chicken coop has been mucked

Okay, so you should muck out your chicken coop twice a year....well it's been a year and we are just getting to it...and when I say we, I mean hubbie and first son. We have a coop that is 24x24 with a wood floor and wooden sides on 3 walls and the 4th is chicken wire that we cover with a clear plastic product used for greenhouses. This gives our girls plenty of ventilation.
