Birds can get overweight, just like humans can. In fact, it’s pretty easy for that to happen, as food is the most oftenly used reward, in place of things like exercise or toys.
You should establish good eating habits immediately with your newly weaned bird, so you won’t have to undo bad habits in the future.
Don’t use food as a reward. Instead, while you’re training them, use a favorite toy or outside (the cage) time as an incentive.
Pelleted foods are more carefully controlled and parceled out than seeds. They’re less messy, too. “Treats” can be melons or apples.
Make sure your pet gets plenty of exercise outside his cage. Even if his wings are clipped, he can hop around in a larger space. Some birds even like to go on walks through the house.
Making sure your pet has a good diet and plenty of exercise makes for a happier, healthier bird.
