This is the newest addition to our flock. My daughter is really hoping this one is a girl, we have had a hard time finding a BR hen. What do you think? About how old do you think s/he is? S/he's a little taller than my 4 month old RIR. But body size is about the same. Are BR usually tall? Our friend said that she was a hen and probably just around laying age. Hope she's right! Thanks for any help!
