I got some bantams from TSC as well, chipmunk like your #3. They appear to be OEGBs. A farmer I know said her husband used to raise OEGB, and if they grow black feathers on their breasts they're male, but the ones with salmon/fawn feathers are females. I appear to have a 3/3 run.Thank you so much for your patience and your help. I adore these babies, no matter what their breeds or genders. But having an idea of what they are is nice.
Orange band is male, blue band female.
Have fun!
