I have a wonderful young male Cockatiel named Gimel, hatched last July, got him last November. He is very personable and friendly with us. Should we get a second cockatiel to keep with him? Would it make him happier? Would it make him less interested in being with us? If we got one, should it be another male or female? What would be the benefits/disadvantages of each? We also have a male parakeet who lives in a nearby cage, so he has another cage bird for company. They aren't friendly with each other, but can hear each other chatter throughout the day. We do take our cockatiel out of his cage & give him lots of attention & handling. The people who bred our cockatiel have more young ones for sale. Please share your thoughts, thank you!
