Good question... Maybe @KsKingBee can answer that.

I only put the meds in the morning feeding, they have all day to clean it up. IF they don't have it cleaned up they don't get any evening feed, that insures that they eat the medicated fed in the morning. I know that others will put the meds on bread, or into scrambled eggs, but it such a treat it is really difficult to know which bird got the correct measured med. So as you like, but I feel more confident putting meds in the feed. If you put the meds in scrambled eggs and add that to the feed some of the birds will pick out the eggs and others will get shorted.
