I have a very broody duck that will lay on anything. Well, I left her alone with her nest full and figured I'd give her a shot at hatching them. I didn't pay much attention to the eggs, not candling or checking them as I figured they'd hatch or die as I've been incubating eggs myself. Well as to why she hatched chickens is I'm guessing the ones I had in there laid in her house. They were all moved out last week to new coops/runs. This morning I went to feed everyone and heard peeping. I got so excited that maybe she hatched out her ducklings but were shocked to find chickens! I took them away because they're so small and she's well over 20 pounds and I was scared she'd hurt them or the other ducks would. I'm shocked but I feel lucky as I had a last egg hatch the 26th with no playmates and now that one has 4 friends.
