Has anyone had to move before with more than just horses, were you able to transport them in the same carriers? And if so were there any issues with temperaments?

Interesting thought. I wouldn't do it, no. Unless it was a comparable size animal such as a cow, I would think that there could be a risk of injury to the smaller animal.

I would be extremely careful with this. What kind of animals are we talking about here? I just think that any animals you transport with horses should be about the same size. I just feel that it would be easy for smaller animals to get trampled.

I was thinking along the lines if you had a farm and ended up moving all of your animals, not like just taking them to a country fair or anything. Full size adult horses, ponies, goats, anything along those lines.
