Hey,
I usually have some soy yogurt at my house, can I freeze the yogurt as little drops and give it to my gliders,
and can I give 100% juices without concantrate or any added sugars? Like apple/pear, apple/carrot juices

fresh water tap or bottled is all the glider need to drink, if they are sick
some suggest Pedialyte I think to help replace lost nutrition.

I give regular yogurt drops as a treat, don't know about soy.
