I bought Americauna pullets 1 month ago - now, one is looking increasingly different. He/she (for that, of course, is the question), is slightly smaller than the others, and the tail points up rather than more straight back like the others. This one was always a little different in color as well - solid chocolate colored head rather than stripey like the others. So, what do you think - do I have a roo, a pullet, or even a bantam roo or pullet that got in with my girls? Any feedback would be great - I can try photos, but there may be a bit of a learning curve on that.
