Challenge - Worms
I've used this product for a few months now I have seen so much improvement in the young birds without the expensive treatment lines I use all three products that are available with a small amount used each day it is very economical and being Natural I believe it is a lot better for the birds
Don't have any problems with birds drinking it haven't noticed any great difference in birds themselves but might be too soon for that.
I breed show budgies and you could see the improvement in the birds.But supply needs to be more reliable waited 3 months to get last order .
