We've had Cosmo over three weeks and he is definitely settling in. I speak with him and he seems unafraid when I am near him or if I place my hand in his cage; he even nibbles millet that I am holding. He still does not come to my hand to explore it and is still untamed. He seems to have so much energy and is frustrated not to be out of the cage. He is in quarantine from Cato (our older parakeet) but when he and our Cato who is in another room "talk" he gets very excited and flies wildly around his cage. He does this other times when by himself. My husband and I opened the cage on two occasions and he came out but flew erratically. He does not act afraid but has poor control at stopping in time or switching direction. When he lights on an object he is calm and sits for a while. He does not seem scared just poor control. Even though we have tried to make the room as parakeet safe as we can, he actually has struck the wall. Thankfully he was unhurt and we do not want him to get hurt. He seems to love to be outside of his cage but we are hesitant to continue to allow it since he has so little control. Is this an instance where we should consider trimming his flight feathers so he can be outside the cage more and learn better control? If we do not trim his flight feathers, how can we ensure his safety?
If Cosmo is tamed, you can begin working on flight recalls and strengthen his flight skills. Eventually, you can work up to flying around obstacles. You can hang sheets a little ways away from the wall so they slow him down if he's going to hit it.
To be completely honest with you, crashing into things is going to be part of the learning process. You fell a few times when learning to walk or to ride a bike, right? Well, it's going to be the same for Cosmo. The best way to keep him safe is to let him continue to fly. This will develop the brain regions that are responsible for flight and eventually Cosmo will be able to fly without any problems!
Links that may be able to help you:
Make sure the room is bird safe.
Cover windows and mirrors.
Tape sheets 4-6" out from the walls so that if Cosmo flies into them he won't be injured.
Part of learning to maneuver well when flying comes from learning the dimensions of the area.
Once he is familiar with the room, he won't fly into things anymore and will have developed his ability to turn quickly when necessary.
