I got some chicks end of July and they are now about 5 months old. I can't tell if my buff orpington is a hen or rooster. I am leaning towards a rooster, which would be bad because we aren't allowed to have them in the city. 6 red stars, 2 australorp's and one buff orpington. I had an orpington previously but she died last Feb and just had to get a replacement, but I am concerned I got a roo instead. Any thoughts would be greatly appreciated. Here they are as chicks Rooster or Hen? As a baby chick Maybe 2 months old here The crown is not very big at all compared to the red stars which lay eggs early 3.5 Months old Here he / she is taken this morning tail feathers means rooster?? -- 5 months old now In comparison here is "Buffy" my previous orpington hen who passed away last year, Feb 2014 the big difference that is concerning to me is the tail feathers and size of the crown. Any thoughts would be really helpful. Thanks.
