I have two 6 day old chicks that I got from a woman in MD who sells eggs on eBay - she has BCM roos and standard Araucana hens - they were purchased to be brooder mates for my lonely AC hatched by me on the same date.
She mentioned that the tailless one was Araucana? and the other was BCM? At what age will I be able to tell their sex and breed?
Here's Smokey at 4 days old hiding behind the feeder dish

Here's Bandit at 4 days old on the left in front of AC her 3rd brooder mate
