Lucy our Rhode Island Red laid the first egg.

From my limited experience, Rhode Island Reds are truly a "Rosy the Riviter". We get an egg a day.
The Orpingtons are probably an egg every other on average. We found Ethel to be our friendliest and most social/vocal girl.
The Amerucana has been fickle. Started out an egg every other, but has gone broody twice and likes to lay her eggs in a "secret nest" elsewhere in the yard, not in nest box.
The Amerucana's are known for laying blue or green eggs. Beautiful and unique, but we won't get another of this breed.
