I bought an 18 week Maran roo. I bought him on impluse because I found out that my little flock of chickens did not include the rooster I paid for. Also, I had researched Delaware chickens and decided those are the ones I wanted. Well I bought Light Brahmas. The Seller said they were Delwares and what did I know when I looked at them as chicks. Turns out the feathers on the outside of the legs should of clued me in. Well, anyway I am keeping them (11) and now going to do my research on the Light Brahmas to make sure they can stand up to the Alaska winters. Back to the roo part, when will the roo start cockel dootle dooing? Also... what is the average age that they start trying to mate with the hens? Thanks
