I let my girls for an hour or two a day. They love to freerange. I have two girls that specifically hunt for frogs that hide under the boulders in the woods around my house. Marge and Nellie first found frogs there by chance but as I observed them throughout the fall, I noticed that while the others were busy scratching around in the leaves and grass, they were specifically digging around the big rocks we have by the house and in the woods. I found it odd until I realized that they were consistantly catching frogs by doing this! Too funny watching them run from everyone with a screaming frog hanging out of their beaks! I dont need an exterminator for anything at my house, I have eight willing feathered ones who pay me for the job!!!
