📏Growth & Size Facts
Bar Spacing
Crucial safety factor. Small birds can get heads stuck in wide bars. Large birds can break thin bars.
Weaning Weight
Baby birds often lose a little weight when weaning (learning to eat alone). Monitor closely.
Keel Bone
Feel the chest bone. Sharp = too thin. Cleavage = too fat. Just right = barely felt.
Tail Feathers
Include tail length when planning cage height, especially for Macaws or Parakeets.
