I have some hens that I have separated due to being pecked by the others. Every day I go in and gather their eggs. I noticed last week one hen had 2 eggs in her nest. Hmmmm? Did I miss one yesterday? Must have I thought. Now today, a week later. Poof! 2 eggs in her nest again. So is it possible for a hen to give 2 eggs in one day? or what my family thinks, my mind has flown the coop.
