About a month ago, I got 6 chicks from the county fair. 2 EE's, 2 BA's, and 2 BO's. One of my BA's was definitely a rooster (helloooo, crow). Thankfully my chicken guy was needing a new BA roo and I needed another hen since I'm still 95% sure my black and white EE is a roo as well (he's a keeper either way). They're all from the same flock, and have only been apart for around 4 weeks. Should I still keep the new one (a white rock hen) in quarantine?
