I got a "grab bag" of chicks and ended up with 4 Australorps, 2 Barred Rock and 2 of these unknowns. Only the Australorps are laying, so I dont know what color eggs these girls lay. I thought the coloring looked like Welsummer, but maybe some kind of RIR?
Thank you for pointing me to leghorn. After reading more about that breed, the description of nervous temperament fits them. Both the Barred Rocks and Australorps are fairly friendly, but not my brown hens. I guess I'll find out as soon as they start laying. White eggs would confirm.
