Winter hay feeder options - One fat, one not
Can I get some opinions?
I have one horse and one large pony. The pony is fat and the horse is not.
Right now they are on a free choice alfalfa/grass round bale with a slow feeder net over the top of it. The bale is in a four sided feeder with a roof and walls that are about 3' tall. The openings are about 4.5' x 5' in size.
Horse eats like a reasonable creature, but Pony is constantly eating like a total lardo. Separating them and forking hay is not an option. When the weather is really bad I cannot reliably get out there (driveway blows shut quickly and the road is one of the last plowed). I have someone who checks on them to make sure they are ok and have water, but I can't ask that person to be throwing hay and filling different troughs. The set up now has no issues other than Pony being fat.
I am considering tarping off three of the sides during the day so that Pony can only eat when Horse is not eating during the day. He is aggressive enough that I doubt he would let her eat on the same side as him, but since he isn't constantly sitting there with his face in the bale she would be able to eat on/off. At night or when it's ridiculously cold I'd have it completely open.
What do you think? I need some other opinions/views on this so I'm not missing anything.
