I have a flock of 7 chickens - 4 bantams including 2 roosters, and 3 standard sized hens. A few weeks ago one of my bannie hens went broody on the floor of the 2 story coop, and I didn't give it much thought. Last week I opened the coop one morning and she walked out with 7 chicks. All the chicks appear to be hers and all are the same age. I thought when a hen went broody she stopped laying. How did she manage to lay 7 eggs that matured at apparently the same time?
