Calcium & Charcoal Bell
Calcium is an essential part of all birds diet to keep them growing and healthy throughout their lives. In seed based diets calcium is lacking which can result in shorter lives.
Calcium bells are an easy solution to the lack of calcium but also easy to administer. Find a hanging spot normally just above the "favourite" perch and done.
Charcoal aids in the digestion process but also removes toxins that the bird may have ingested. Charcoal & Calcium bells are white or even a slight grey tint.
