I have 5 chickens, all about 7 months old. Only one is laying. I originally had straw for bedding, but after our banty had an impacted crop we pulled all straw. Then I started using wood shavings, everyone ate these like crazy, so I pulled those too. It was fine in the summer to have a dirt floor, but we recently moved to a much colder place. I put down sand and that was working well, except today we are having a high of 25 and down to 10 tonight. My chickens were shivering a little, so I knew I had to put something warmer down for them. They are all scratching around eating the shavings. Will they stop doing this at some point when it ceases to be new and exciting? They were immediately much happier with the warmer floor, so I hope no one gets impacted, I do not want to deal with that again!
