We had put some cardboard boxes in the runs to act as windbreaks against the cold winter wind. Seramas do okay against the cold but if it’s windy, then that can be a problem for them. But as you can see in the picture, the cardboard has absorbed moisture from the air over the past 6 months and is now sagging and looking pretty ragged. So it was time to take them out and I also roughed up the runs with a hoe, to aerate the soil and give everybody some new ground to scratch on.
