I am writing because I wanted you to know that Higgins has reformulated their Sunburst mixes.
They used to be only in 3 sizes but they devided up the large size into two sizes.
The Large size now is in two formulas Parrot (for greys, amazons, etc – more loose meats and pieces and not the large nuts in shells)
and Macaw (for largest birds, Macaws, Large Cockatoos which contains more large nuts and large fruits and veggies etc.
The whole mix is improved for the 4 types now. The current ingredient panels are in all the Sunburst listings.
