Hello from northern Montana! I acquired my first three hens last spring, so this is my first winter tending them. We have a nice shelter for the winter and they stay inside mostly, but they are getting verrrrry bored. Where I used to be greeted each morning with a cheery "Hi Mom!" now the sounds are more like "We're cold and bored and pretty sure it's all your fault." I decided to string up some garden tomatos so they could peck at them, and they were gone in moments. What are some good DIY ideas for keeping my girls occupied? Popcorn balls? Scratch balls? A pit of dirt with worms? A music loop with subliminal hypnotic messages? Thanks in advance. I never thought I'd be taking care of chickens, but we really like each other a lot.
