The correct Beginning:
When starting with a baby bird (chick) it is extremely important to interact with the baby, as you will be doing throughout its life. This means that you spend the time with the cute little baby that you will have to spend with the adult bird. Many behavior problems are thought to arise from a well-meaning owner spending every minute of his/her spare time with their new adorable baby and allowing them to rule the house. Problems arise when the bird becomes an adult and suddenly is no longer the center of attention.
I encourage my clients to start from the first day by establishing a routine for their interaction with their new bird. This should be a routine with which they will be able to follow throughout the bird’s life. For instance, I recommend not rushing to the bird’s cage the instant you come home because this teaches the bird to expect immediate attention every time you walk in the door. You want the bird to be comfortable both with and without your constant presence. A well-adjusted bird will play happily in its cage as well as with you.
Also, start from the beginning by introducing new objects into their environment such as toys and exposing them to new people and situations. This helps to desensitize the bird to change later in life.
To fly or not to fly:
Some avian experts believe that in order for a chick to grow into a confidant adult they need to learn to fly. Flying not only builds muscle, but the bird also learns to navigate and seems to promote balance and the development of confidence. This method utilized a delayed wing trim on young birds. The bird is allowed to fledge out and learn to fly. I recommend teaching your bird to come to you on cue at this point or you’ll be forever retrieving them form topmost areas of your house. Once the bird has gained a good flying ability the outer few primary wing feathers are gradually clipped until the bird is no longer able to gain lift. I do believe that this result in a better emotionally developed bird, but if you decide to utilize this method of raising your bird you must understand the inherent danger. Young birds will have no navigation ability and will fly into walls and windows to they should only be allowed to fly in a "safe" room and they should be kept out of kitchens and bathrooms – full of dangers to the young flier. Of course, the primary danger is that your bird could escape the house and be forever lost. For that reason, I don’t recommend this method if young children are in the house (it is just about impossible to always watch for the open doors). And this is another reason the bird should be taught to fly to you on command early in life, but realize that a frightened young bird that escapes the house may be long gone before you can call the baby back.

Enrich the environment: Foraging Behavior is a MUST for all pet birds
Because we want our birds to be content in their cage during the times that we cannot interact with them, it is important that the cage be a fun place to be and not a prison. Enriching the environment means providing distractions for your bird in many different ways.
