My 13 girls (dob 6/2/11) BR's, Dominiques, Speckled Sussex, 2 roo's(meat) along with the my female runner duck and 2 drakes have been free range since they were about 6 weeks old.. on 9/2 my female runner duck laid her first egg, yeah , duck-duck has been a steady layer since, at a egg a day. Some double yolkers; sometimes 3 eggs in 48 hours...seriously. My girls, on the other hand, dont seem to be very interested in the whole egg laying sceen..I dont think. They have gotten all red in the face..no chicken dances or squating but still nothing in the nest boxes. No signs of eggbound or any other health issues. (other than roos)I've tried changing straw, not changing straw, I left a duck egg in there to give them a hint too, Increasing/decreasing the size of the boxes...nothing. They all come in at night on their own, usually. I offer free choice oyster shell, feed all flock 18%, abundent scratch grain and I also offer tons of fresh mellon rinds and salad bar left-overs which get gobbled down. If they are hiding a nest, I sure cant find it.. I have gone around the yard like a weirdo looking in all the bushes for signs that they are laying in some secret place..but nothing, dust bath wollows and resting spots but no eggs in them. With the days getting shorter I put a natural grow light in the hen house now and I am seeing signs that they have been in the boxes but still no eggs. Any other suggestions on tricks and ploys to get the girls to perform? Honestly, these will be $300 each eggs when I finally get them if this keeps up!.
