How high can raise chicken tractor be raised during transport without chickens escaping?

Quote: A LOT less than you think it can.
You're taking a big risk moving it around with them inside and not confined to a small enclosed area

 

We wait until the girls are in the coop portion and shut the coop door before we move the tractor. We go veeeery slow and haven't knocked anyone off the roost yet. The only down side is that we have a very short window of opportunity to move it, we have to be right there when the girls go in at night. Guess you could move it in the morning before letting them out.

Wouldn't want to move it with the chickens in the run portion. Too much of a risk of them escaping and - worse - a bird getting injured.

 

My tractor raises about 4" and then rolls freely. I can easily move it with the layers down on the ground - they just walk along. But the Silkies.... Dear Lord, the Silkies.... They refuse to walk with it, and instead sit down and let it roll over them.

There is nothing magical about the mechanism that raises/lower my tractor. If you want close-ups of it so you can re-create it, let me know.

 

Please?

 

Even if the chickens get out they will not go far, and as soon as it starts to get dark they will go back in the coop...But it would have to be really close to the ground to keep them inside the tractor.

 

I will try to get some tomorrow in the sunlight...

 

My question is how will I get them from the coop with a covered run into the tractor?
I imagine it will be quite a sight the first few times.

Here's hoping they follow the cracked corn.
