Our Americauna is about 30 weeks...about 6 months. All our other 7 chickens are laying and have been laying for the past month. (3 Buff Orpingtons, 2 RIR, and 2 Bantam Cochins). We keep looking for a green egg and nothing yet. My husband said he saw her in the nest box yesterday and the day before...but, still no egg.
