My 2 chickens are 22 weeks old - they are my first. They sleep in their coop at night, but I let them run in the yard during the day. I am dying waiting for them to start laying and I'm afraid they might have a hidden nest and I'm missing it. I know I could keep them in for a few weeks, but they love being out so much. Are hidden nests hard to find? I have an Americoura and a Buff.
