I bought a duck Thursday that's laying eggs. I went into the coop yesterday and found one laying in the middle of the floor that was absolutely filthy!! My chickens lay their eggs in the enclosure in their coop. It's very spacious and more than big enough for the duck to go in. Most of the time, my chicken eggs are clean and pretty. So I'm not used to seeing eggs dirty like this. My coop is pretty much always clean so I don't know how she got it this filthy! Are all ducks like this?!
