This is my first spring breeding season and the birds have me confused, already. I have a blue check cock that naturally paired up with an indigo bar hen. I noticed the nest building and consistant driving of the hen. The indigo layed (what I thought was hers) her eggs but when I entered the loft last night, I found 4 eggs and one of my solid white hens sitting on the nest. The indigo was also next to her. So my question is, has anyone had this happen if so is it common?
