Thanks so much for all of the replies. I have to say that I'm beyond tickled with everyone's guesses! I know that only time will tell for certain, but it makes me smile to think we may get to keep 4/5 of our straight-run chicks.
For those who've said they are pretty, thank you! They came from our fellow BYCer HorseFeatherz (Genny) and I've been very impressed. These little birds have seemed so much friendlier and sturdier than our feed store chicks last year. The variety has been a nice treat, too!
Wishing everybody a happy Friday!
