I believe that one of my hens is going to lay her first egg today. I have 4 BO hens and so far only one of them is laying. She has been for 3 weeks or so. I've noticed a lot of egg laying behaviors from the other hens but no other eggs yet. This morning I heard egg song 3 times. I thought it seemed unlikely that all 3 remaining hens would choose to lay on the same day. Every time I went out there were no eggs. So my 2 year old and I went out to look for a hidden nest and found nothing, when we went back in the barn I heard the egg song again! The hen was in the barn by the nest boxes making a huge fuss, but there were no eggs to be found. It's been this ONE HEN making the egg song all morning long. She reminds me of a woman in labor, pacing around, kind of unsure of where she wants to be. THe rest of the flock dutifully congregates whenever she sings her song and sometimes they join in, it's pretty cute. Has anyone had a hen sing the egg song BEFORE laying???
