I'd add Dominiques to the list. Active, great foragers, hilarious, very busy on important hen business, and quiet and calm despite being very active. We refer to ours as the Unite Clown here at the Cirque des Poulets because they are so funny and adorable. Eggs are a little on the small side compared to Barred Rocks or Black Star hybrids, but they make up for this with their curious personalities.
If a person's primary goal is eggs, what would be the advantage of a Dominique over a Barred Plymouth Rock?
Barred Plymouth Rocks lays an average of about 250 eggs a year.
Dominiques lay an average of about 220 eggs a year.
