I'm new to the chicken raising fun and right now I'm having a total blast! These chickens are so entertaining. Anyway, I have been wondering about chicken laying habits. In all the posts I have read, chickens will sometimes lay where ever they want. We have three that are about 17 weeks old and so I put some nest boxes in the coop. They haven't shown any interest in the nests yet, but I'm being patient. I am a little concerned though that they might decide to lay under the coop. I didn't build it with a lot of crawl space, but the chickens can and love to go under and relax in the shade, far from my reach. We are experiencing a historic heat wave right now in North Texas with records being broken daily. Even though the run is shaded for most of the day, I know that the chickens are staying cool under the coop. I would hate to block off the crawl space to them right now. Should I be concerned about the chickens deciding to lay an egg there? If they do, I will never know about it.
