What kind of trailer was it? and how did you/they approach it?
I need to be quick here, but we put Misty in first, no problem, then we had thunder in the round pen and led him to the trailer and kind of closed the round pen a little behind him. He then went straight on in and started to feed. (very hungry!) they then came back with Misty after dropping Thunder off and we did the same with Adge. I am just so glad that it worked out so well.
I have to go help with Lightning now. : )
