I have no idea what kind of chickens these are and they are already almost fully grown(I think). There are three of them. 2 of the three have a light golden yellow head and as you go down their body it becomes dark brown/black with some yellow spots and at the very end it is black. The last chicken is a reddish brown from head to tail,except her head is a little more orangyer then the rest of her body. Thanks for the help!
