Hi, I'm a first time hen owner, I got 4 hens back in March. I have a coop with a small run which they sleep in at night, but they have the full use of my garden from morning until night. It's really well secured and predator free. To roughly describe my garden, there are 2 grass patches, each measuring approx 18ft x 18ft, on either side, with a concrete path down the centre of those 2 patches with another strip of concrete at the bottom of the garden beside the entrance to my home. After many months with the hens, the grass is now just mud, and at this time of year in Ireland, it's very wet out too. My question is, is it bad for my hens to always be walking on either concrete paths or soggy mud? Will it have any negative impact on their feet? Any advice would be appreciated if this turns out to be an unsuitable surface for them!
