Oh yeah. They're the main reason I had to put my chicks out. We have 4 and each has a colored drop of food dye on them, but we need a better way to mark because that lasted about 3 days. Yellow, Chrystal, will fly up on you and roost on you. She's the most likely to do that. There combs are getting a slight pink hue to them now. And they're growing fast. They're still small compaired to my Red Rangers, though.
I LOVE my chickens. I wish I could have more ... lol. Some Barred Rocks!
