hi all, so i have 4 BRs who have all been growing very nicely. they are 8 weeks old now, and i noticed just yesterday that the biggest of them all (she has always been the biggest), Big Bertha, has an all black flight feather on each wing. in the sun it's green/blue. up till now i was pretty sure they were all hens. she is definitely big and a little farther along in comb and waddle development than the others, but given that she has always been growing the fastest, this makes sense to me. she has the black feathers with the light white barring (i.e. more black than white), just like all the others. she has a dark splash across her feet just like the others. she is shaped just like the others, though a little bit bigger. is it possible, bertha is a roo? do hens get blue/green feathers ever?
