I give Finn pallets three times a day along with his veggies also three times a day. This is his daily routine so there is nothing left in his food dish. He does have endless supply of hay.
Lara on the other hand, when she came home with me from friend who didn’t want her, used to only eat pallets and hay. She never had veggies or fruit. So, her pallets have to be in her food dish all the time. I don’t want to change things too quickly for Lara so, despite the fact she gets veggies three times a day I still leave a full bowl of pallet for her. She also gets endless supply of hay.
