Here are some more recent pictures. Still hoping to get an idea of hen/roo and maybe what breed. I keep telling my son they are mutt chickens! lol He says, "Mama, stop joking me. What are they really?" To which I respond "Chickens".
The 2 chicks in your bottom pic look just like my Wyandotte chicks... if they are black they are silver lace ... if they are brown then they are blue laced red Wyandottes.
