I've gotten a white egg out of the trough nest for the last 4 days, I only have one white egg layer and that is Duchess,, she lays her egg every day in HER nest and that is that. So where did the other white egg come from? We got a clue last night! We got home late so it was dark and the birds ate late... All the tree chickens came leaping out of the tree to eat, except for one tan colored chicken butt that I thought was Duchess,, then I realized Duchess and her baby DB (Duchess' Baby) were eating out of their hanging bird feeder so that couldn't be her! Up in the tree all by itself was Duchess' twin! I don't know where she came from or how long she's been hanging around because you can't tell them apart and they've never been next to each other or I would have thought I was having vision problems! Duchess is the hen that walked down the road last year and into the yard and stayed,, I guess this one probably came from wherever Duchess came from.
