Good morning & welcome to BYC.
Mine would not drink it so I mixed some with water and then mixed that in with some feed. (So of course they had plain water available too) They ate every bite of the feed.
As stated above don't use it every day. When mine need to regrow feathers, I generally feed mine canned catfood or fish once or twice a week. Sardines, tuna, or salmon all have protein to help with feather growth.
