I have two Mille Fluer D'Uccles and two Red Cochin hens that will totally empty out the nesting area of the coop. I have put pine shavings, and straw both and even some hay. but they will scatch kick every bit of it out of the nesting area of the coop leaving it completely bare I mean they do a better job than I could do with a broom! even in cold weather they are laying their eggs on the bare wood which of course leads to frozen eggs. but more importantly it drives me nuts trying to figure out why they do this. Our big girls in the other coop like to nestle down in the pine shavings to lay eggs. is it just a bantam quirk?
