Hi! i recently got a female i (think but its too young for a dna test) cockatiel and was wondering if i were to get more birds (most likely more cockatiels a pionus and ekkies) if they would be able to become friends and if so how to do that. I wont be getting more birds for a while since i need to find a breeder or someone who would sell them and also need to do more research on ekkies. And also if i were to do that should i get a male or female if it matters for them to be friends.
