I have a year old buckeye cockerel, a three year old Plymouth rock, three red stars (that are a year old), a buff orpington (3 month old), and four silkies (4 months old).
I recently bought four pullets from a local farmer. But as they are getting older they are getting closer to breeding age. But im prity sure I have a cockerel and three girls. He's bigger, getting waddles, and the crown isnt filling in like the rest of the clutch.
