Help! I thought free ranging was the best for them, so dh built me a wonderful door off the run to let them free range supervised. I'm watching them and they go through the yard looking for wild mushrooms! I catch most of them and I'm able to chuck the mushroom into the woods. Sometimes the mushrooms go right down the hatch! I have a very big yard, so finding every mushroom before they head out seems to be an impossible task! These darn things appear every morning! Will the mushrooms kill my girls? Are they that poisonous? My d'uccle found the cutest little mini mushroom just her size. Luckily, I grabbed it quick.
