So I filled two nets and hung them in the run in area...
Musical bags were played frequently the first two days. Merlin would "think" Pippins bag must be giving more hay, due to Pippin be perfectly content. He'd chase Pippin off, rinse &!repeat often.
They still have access to their field, using their nets before heading out at breakfast,when the weather keeps them from wanting to venture out & in the evening.
With Camryn she'd be in the paddock thru winter, her huge feet wouldn't be kind to the ground, her appetite wouldn't have allowed grass to rebound. I'm hoping/thinking the Mini's won't destroy the field. And having room to run means fewer arguments. Yup, they still behave like siblings!
