Please look at these pictures and see which chicken looks like your chicken.
I chose pictures that looked like your hens
The brown one could be a production red
the speckled one is a barred rock
The black one looks like a black star or black australorp
the blue one looks like a mix between a blue andalusian and something I could be wrong
the white one could be a delaware or columbian white
