In our coop we have three- Honey, Omelet, and Puffball. They are all yellow buff orpingtons. Honey has had a crooked beak since birth, Omelet is a skinnier one, and Puffball is a bit chubby. :D We love buff orpingtons too.
We currently have a coop of 7 chickens- three buff orpingtons, two speckled sussexes, one dark brahma, and one medium brahma. We have heard them for around 2 or 3 years and spoil and love them.
