How do you know for sure when a hen will stay on the nest to hatch eggs? I've had a red sex link on and off the nest today quite a bit. If she does decide to hatch eggs, what should I do first? I get 4-5 eggs a day, but I would only want chicks out of 2-3 of them. Would I just pick the eggs i want from the ones I get each day after she starts sitting on the nest? This is my first flock. I have a 2x3 hutch that I used the for the flock when they were little, and I've kept a sick hen in it overnight once. Would I put her in this with the nest? It still gets below 40 degrees F, so I would really need her to be serious about hatching chicks.
