About three months ago a purchased 2 chicks, I was told that they were all hens in the brooder, so I grabbed up 2 and didn't think anything of it. Although I'm an in inexperienced chicken owner I did notice the drastic appearance in my 2 growing pullets. Even as same age chicks on was bigger, much bigger. I inquired about the difference to my local feed store owner, I though maybe one was a mix or something, but he said it was unlikely that the hatchery would make that kind of mistake, maybe one was a bantam or something. We'll fast forward a fee months and one has a large well defined comb and long tail feathers, and the other looks like you would expect a pullet to look at 3 months old. Again, I didn't think much of it, I only have two, they are pets and not bein familiar with this breed of chicken thought it could be a breed characteristic. It wasn't until I posted pictures on Facebook and got comments like, "I want chickens too, but only hens" and "that looks like a male" (from other people that don't have chickens) that it started to dawn on me that maybe my sweet, hand raised pullet might actually be a rooster! Now that I'm thinking about it I'm noticing things that are making me think twice as well. Like I've seen the hackles raised on the one in question and I've seen him/her put the small pullet in her place. The bird in question will also regulate my bunnies when they get too close to the coop or are Co mingling in the yard. It's never tried to bite or shown any sign of agression toward humans. So I'm looking for an expert opinion. Thanks.
