More eggs than birds is a GREAT day!
My Mallard girls occasionally lay their pretty mint green eggs in the nesting boxes.....I guess it all depends on their mood, since they lay all over the place most of the time.
Ah, if you find a definitive answer to that you've answered one of the great mysteries of life! I wonder if it isn't like married couples finding early on which side of the bed they want to claim, and never deviating from that no matter where they find themselves - Aunt Bertha's guest room, motels when on vacation, etc. I'm teasing....actually they do this because they feel more secure laying where they see others already have. They want to build up a clutch and they don't much care that not all of the eggs in that nest are their own. So when they see an egg or two, they figure this must be a pretty safe place to start a family. I have 28 birds and 5 nests. They use 3 of them. Go figger!
