Hello.... a question on amount of minerals that should be eaten .. First let me tell you situation i have 20 head in about 60 acres lot of diff stuff to eat , i keep 3 kinds of salt out for them (white ,yellow ,brown ) also keep a mineral lick tub at all times ,and a mineral feeder free choice with MFA mag meal. the mag meal is not getting used hardely at all. the lick tub (200) lb has been in since feb this yr.. i guess my question is should i pull the salt and make them use the mineral feeder or do any of you think they will eat it if they want it thanks
