The dark colored chick is Betty Ann, and the light colored chick is Elsa - both of those ladies are Ameraucanas.
The other two are Florance and Marjorie, they are RI Reds. Florance has the three dots on her head.
So far they seem to be adjusting nicely to their new home and they are making all sorts of happy little chickie noises. Herky and Lola are less than keen on their arrival but so far they haven't tried to make them part of their evening snack, so I consider that an accomplishment.
And Joe called yesterday... the chickens can stay :)
