Yeah they're getting along really well. Bonnie thought that Toby had risen in the herd to leader because he was actually eating before Gracie was.
When I was out there today, Gracie ate first. I made Toby wait until Dot started eating before I let him at his pile of hay. I worry that Dot won't get enough with the other two there and she's the one who needs it the most because of her age.
