Could you get individual pictures (with our a net)? Also where did you get them? The small brown one *maybe* a Old Egnlish Game but we will need a better picture to be sure. The other three look like Cochins but i think they might be Cochin mixes.
My six older chicks are from the same place so will be the same breed. Same as my bantams will all be the same as each other as from the same farm. We were possibly thinking the bantams could of Golden Pheonixs but totally unsure.
