We aren’t sure. They were just from a farm who has free range chickens on site. So a mixture, was trying to work out what the could be. The black I thought maybe a Wyandotte? As she’s much more slim than the others. I have no idea on the blue/grey and she’s a bit bigger than the others.
We now have our 4 chicks at home. They are mixed breed but trying to workout what their main breed could be. I think they are all Cochins but not sure about the grey one, she has some speckled Sussex about her face. Black looks like a gold laced Cochin/pekin.
