We have a silkie mix, 14 white leghorns and 3 pekin ducks that could be the right momma... we found them this morning in the chicken coop, but one was buried in the dirt and the other was just outside the coop on the dirt. A couple of the leghorns have gotten curious about the nesting boxes, but I thought they were supposed to lay solid white eggs? The leghorns and the ducks are about 4 1/2 months old now and the silkie mix is about a month older. Any ideas? We're so excited to find these!
