I am thinking about switching because the Blue Seal is a little more then 15 dollars here, and I believe the Southern States layer is about 11 to 12, but I would need to recheck when I go to look at horse feed. But I don't want to skimp on the quality, although I have read people like it well enough. If I do decide I would like to get it soon so I can mix and start the switch from one feed to the other. So what are y'all's opinions on these two feeds? How was egg production and how was fertility with each?
