Some of my horses are on pasture exclusively at this time of the year.
Other of my horses need more calories than my pasture provides so they come home and are fed feed daily as needed.
A vitamin/mineral fed to those who maintain a good weight on just pasture.
If unlimited pasture is available...the horse{s} may not need more, or they might.
Hay available is fine if it can be kept out of sunlight, off the ground, dust-free and they'll eat it.
My horses absolutely prefer the pasture to hay...they just do.
If I bring my horses in for any length of time then I do supply hay in several piles for them to eat...
Being honest, I get dirty looks and the hay is more messed with than eaten when they come in with full tummies from grass though...

If the horses are kept in for days then they do eat and eat all offered hay...but they do "voice" their preference in body language standing at the pasture gate.
They do willingly come stand at the feed-room door though looking for feed specifically if I'm in that location...
Watch your horses appearance carefully.
Take pictures, do tape measurements so you can record weight loss or gain. Keep a written record as you learn what each horse needs to thrive.
When we "see" our horses daily it can happen that changes take place and they not be seen till a real marked difference is in front of us...obese or underweight...neither is good for the horse.
Maintaining optimum weight is a art and science for many of us...learned over time to get it "just-right".

Enjoy the new journey in front of you of horses home and all under your care...
I happen to love it and hope to never go back to boarding care...
