Hi! I am very new to chickens - this is my first ever flock! I got the Murray's Choice Layer (I understand this was formerly called Rainbow Layer) assortment from Murray McMurray (asked for all female, we'll see as time goes on what I've actually got gender-wise!). The description states it can include "White Egg Layers, Heavy Breeds, Ameraucanas, and Rare and Unusual Varieties", but it won't tell you who you've got, which was part of the fun. We're a few days away from five weeks old. I'm new to this, so I'm pretty puzzled by everyone (I got 18!), but especially this little black and white number. Any guesses?
