The speckled one looks like Barred Rock(BR) but I'm not sure about the other one. Kinda looked like a Rhode Island Red (RIR) but then it didn't and I am not real good about breeds of chickens.
Welcome, you'll have tons of fun, with your chickens and here on BYC!! Chickens make excellent pets, so many personalities and they like to follow you around.
Have fun and keep us up to date!
