Gotta a few now 3monthish pullets from a home farm and this one is growing like CRAZY. I have two 2 FCBM and the other is the runt of the flock, but this one has grown like a weed in the past 3 weeks. Including the copper hackle feathers where other just got copper peaking through. I've looked at the hackles and tail feathers and they seem hen-nish, but it has cankles to me lol. Compared to the other FBCM I think she's a fast maturing pullet or a sneaky fem roo What say yall? I tried to show all the key areas. Hoping for a pullet as I'm an urban chicken mom! EDIT: She COULD be 8/9weeks old. The farm said 2months, but I'm not so sure.
