Yep, I seperate and wait until Sienna (the old girl) has finished her feed to bring them back together. Piper (the young girl) basically gets a charity feed so she doesn't feel left out and I add apple cider vinegar and garlic to it :)
I separate my horses in the paddock for feeding, but I feed hay. I have several little piggies and a couple slow poke eaters. It does involve two trips 2 x a day. But otherwise some go hungry and the others get fat.
Our guys are stalled during the day, so I pull them up, feed and hay, and they spend the day, then I feed again, let them finish and go turn out. Nighttime hay is eaten under the trees, and is pity hay, so I let them share. Posted via Mobile Device
I never separate my mares when feeding pellets. Even though my qh is a fast eater and very alphish. She's trained it's a BIG NO-NO to chase the paint from her bucket (paint is awfully slow eater). So qh when she's done basically stands by paint's side waiting till paint finishes and steps away (then it's time for her to lick the bucket). It's actually quite funny to watch, because qh keeps one eye on paint (when she finishes) and other one on me to see if I'll disappear (THEN she can chase the paint away). :)
