I am currently feeding Southern States Start-N-Grow (medicated). My local feed store sells it, and as it saves me an hour trip to get to my nearest TSC, so I started feeding it. And they seem to only carry SS feed. I read in some post on here that he or she experienced lowered egg production when feeding SS. So I'm wondering how many of you out there feed it and whether or not you like it. Thanks so much everyone! I just want to know if I need to switch brands when I get my first bag of layer feed.
