Yay for more pygmys!! Make sure you don't just throw everyone together though...you should quarantine your new arrivals separately for at least 30 days before introducing them to your lonely female. As wc specimens from unknown origins you don't want to inadvertently put unhealthy animals in with your healthy one and unknowingly give her a disease. They can look healthy at first but stress can exacerbate underlying issues like parasites or viruses. It's tough waiting on quarantine, but could circumvent some bad outcomes! Can't wait to see the new recruits!
