This year we are new chicken parents and we have 3 young hens (7 months old). They are a Rhode Island Red, Silver Laced Wyandotte and an Easter Egger. Up until about 3-4 weeks ago, all three hens were laying about 3-4 eggs per week. We noticed that the Easter Egger seems to lay a double yolk egg about every 4-5th egg she lays.... thats no big deal but she hasn't produced any at all in about 3 weeks or so. We live in Maine and it is getting colder and darker earlier and we expected a drop in production. The other two continue to give 2-3 each, every week but the EE just seems to have stopped. Is this normal? Thank you for any thoughts, suggestions or tips.
