...twice. Thank goodness it was the tractor-coop and not the Masey Ferguson. The poor thing just couldn't grasp the concept of "when the wall moves towards you, you have to walk the opposide direction". The first time, the coop rolled right over her and she laid in the lawn confused. I scooped her up and set her on the perch inside the tractor and started moving it again. She promptly hopped down and fell under the moving wall again. (sigh) So, I picked her up and set her on the top of the coop as I rolled it across the yard. The other 7 babies marched very well in the rolling coop to new grass. She seemed happy to ride on top looking at me. I put her back in the coop after I moved it and she was still moving around sort of slow. I hope she wasn't hurt too badly.
