I have my F Albino BP and my F Normal BP living together in a terrarium right now before I move them into racks. My girls have always been so friendly and loving towards each other but yesterday I noticed their tails locking. I've sexed both of them many times and have always gotten girls from them, never any hemipenes. Is it normal for 2 females to lock at a certain age just because it's a familiar feeling or is it because they're coming up on the age for them to start breeding. Or is one of my suspected females actually a male? I have pictures but no idea how to post them.
