I'm guessing exploring. My oldest hens, rhode islands, were hatched during the 3d week of June. There's no sign of one being a rooster yet. Once a week I deep clean and sanitize their coop. Their nesting boxes and sleeping roosts (more down the ramp) are on the second floor. They are happy spoiled girls. They free range during the day and put themselves to bed. Last night I let them stay out until they chose to go upstairs. I listened, a great deal of trilling back and forth. "Goodnight John boy. Goodnight Grandma..." this morning when I went to clean the top of the coop, every one of the 8 nesting boxes with alfalfa hay was well patted down. Only the one closest to the ramp had poop in it, sO think that one us a pecking order distance sleeping w/ the flock thing. But I think they are way to young to start laying. Do they sometimes do this just to pick a fav spot?
