you need a square-sided bucket. Get one that Strongid comes in from a horse friend, or get a rectangular water storage container That has a perfect spot to screw the Tee into.
Thread the tee and nipples with white Teflon tape. Good luck!
It depends if you are raising layers or broilers.
I'm still trying to figure out the best ratio of grower to finisher for broilers.
For all chicks: Starter feed until one bag runs out (a couple of weeks for broilers, longer for layers).
Mix starter with grower to transition them to new...
