Hi there I give my bird's Kilpatricks minerals in finger drawers all year round, it contains charcoal and some of the bird's take it others don't ,only drawback is birds faces can resemble that of a coalman so keep it away from your show team .
Tommy I would recomend Kilpatrick minerals have use them all my days in the fancy I'm always amazed when offered to the birds in the flights every bird immediatly is down for it it contains charcoal and a variety of salts.However just a couple of weeks ago I called into Somerviles for seed and also Kilpatricks Min. he told me it was no longer available, (though I've heard that before," I took a product by Aviforme, Black Minerals termed free access minerals in it's place this contains, phosphates,lime,potassium salts,iodines and charcoal, it sounds the part but I did notice the birds took to it but not with same keeness as the former.

I get mine from Allan Melvin as he also supplies my seed,will ask him if it is still available this week and will let you know what he says.I also give them Terramix which has lots of good minerals in it,the birds dive in as soon as dish is on the flight floor .
