We have a few questions: 1. We 1 Buff Orpington and 2 Americanas - AND THEY JUST LAID ONE EGG (we are not sure which one laid it Any clues how many eggs we might start expecting? 2. What is the difference between Americanas, Americaunas, and Easter Eggers? 3. We want to start having them lay in the nest box, but can't seem to get and keep them in there to lay - any clues? 4. We may want to introduce other breeds to this group... Anything we should avoid?
