We have a Wyandotte, a Bantam Barred Rock, a Buff Orpington, and a Bantam Cochin. All lay brown eggs. The banty Barred Rock lays and egg a day all year with a brief time out for molt. The Wyandotte and Orpington lay almost every day. The Bantam Cochin is a great pet, doesn't know she's a chicken and probably thinks it is beneath her to lay eggs!
