I am getting ready to build the nest boxes for my pullets, the oldest of the Rsl are 14 weeks old, and the youngest are 11 1/2 weeks. First of all, if they are too young will they roost in the nest? (I have read that the Red Sex Links may start laying any time after about 17 weeks of age.) I also have more then 130 cockerels, (For freezer patrol!), and 19 turkey poults they are all about the same age. (A few of these will join the Freezer Bregade next Fall!) Will I have a problem with the turkeys or the boys using the nest? I plan on making the nest 14 1/2" wide due to the fact that the wall studs are 16" on center, and these nest is being added to the outside of the coop for easy egg gathering, 14" high, and 16" deep, and 24" off the coop floor to the bottom of the nest. I am starting with 7 nest, with a design to add 7 more on top of these if needed. Does this sound like a good design, or should I rethink it? The turkeys will not start laying for a few months, (6-7 months most likely!) and I have a large dog house (28"W x 36"L x 38"H at the peak, with a 14"X18" opening, all wood construction including a wooden floor, and shingled roof!) I plan on placing in the run when the time comes for the turkeys to lay.
