Hi . I'm mom to 4 beautiful Buff Orpington hens. They are about 5 months old. This morning a couple of them, especially one, became extremely vocal. She has been carrying on all morning! They are fed, watered, and free ranging. I'm wondering what all of her fuss is about and if she is letting me know that she is ready to start laying. She also started the submissive squat. I went out to see what the fuss was and she squatted for me, she has been squatting for a couple of days now... I don't have nesting boxes yet because I thought it would be springtime before I got eggs. Should I rush to get nesting boxes or will she find a place to lay? Could she be vocal because she wants a box? Thanks
