Thanks for your prompt replies. I was just afraid that the shavings wouldn't be enough cushion for the eggs. But it's just one less piece of chicken paraphernalia I need to worry about!
I have had my five hens for 17 weeks now and they are getting that red flush everyone talks about before they begin laying. There are nesting box liners for sale out there. Does anyone use them or should I just use a mat of pine shavings that I already use in my coop? Thanks
