Both Blu and Charlie appear as young females. Charlie (from the more distant) has a cere that is pale whitish blue(female). If you have a closer photo to show of Charlie, I would be positive.
Thanks Everyone!! I will definitely get them another cage, however they are not tamed yet. I reading that it's best to have them in separate cages to be able to Tame them. So I just separated them a couple of days ago. Would you recommend I purchase two bigger cages for now until I tame them, because before being in the same cage together they were bonding with each other instead of me. Both of them would run. Please help. I'm so new to this but I do want them to be very comfortable in their homes.
