Does anybody know what this is?

I am wondering if regular milk would work too? My chickens gobble milk up like no tomorrow ...

I would have gotten corid, but 4 different feed stores around town were sold out of the stuff and sulmet, and there was only one bottle left of the sulmet at one of the feed stores. So either way sulmet and corid are pretty good stuff. I'll try that milk tomorrow when I feed everybody to see how well it works, it does make sense using the milk its a good idea. Thanks
