I wish I had another brahma in my flock to compare her to! I've got all different breeds. :-\\ Thanks for all the feedback! She is a standard size, and yes, 8 weeks old. She was the slowest to feather in (but again, all different breeds!). She was a little weak after she shipped and she almost didn't make it. With lots of tlc, she pulled through and is now the 2nd largest, after my easter egger.
She has been full of drama since she arrived! We named her Madonna and with all her antics, she's now called Madonna Drama. She's the silliest bird we have - the last one to learn how to climb up into and down from the coop - and has the funniest way of flying... almost like a little helicopter - she flies up and with a twist. She is a crack up, and we love her... so we REALLY hope she gets to stay! (no roosters allowed in San Jose)
