I had a question about eyesight. Is it possible that a cockatiel can be born with bad eyesight? My cockatiel back home, jumps and climbs very efficiently, but my new bird seems to fall as he tries to make his way to lower perches or just plain climbing he seems timid and slow, constantly hanging or missing the perch sometimes. When he climbs the side of the cage it seems very strenuous for him and almost a chore to get to higher perches. Although when it comes to flying he knows exactly where he is going as he always seems to fly to me mostly out of all three members of the household. Could it be that he is still fairly young, roughly 10-11 weeks old, and that is the reason he takes his time or stumbles or falls in the cage trying to reach perches?
