Thanks for sharing that, Syl. I will watch for that. Certainly don't want any preventable injuries.I had one Silkie bantam that would scratch the wood nestbox bottom so hard before laying her egg that she would pull out toenails or injure toes to bleeding so we had to use plexiglass bottoms on the nestbox bottoms to keep that one Silkie from digging splinters into her toes. We tried other material but her toenails even snagged plastic so we resorted to plexiglass hard bottoms. She hasn't injured any more toes since. It makes the bottom of the nests slippery so extra straw or shavings will be necessary to keep the other chickens from slipping and sliding on the slippery bottoms. They've pretty much all gotten used to maneuvering around on the slippery bottoms. One thing I've noticed is that it was easier to clean up a broken soft shell egg on the plexiglass where it might've soaked too much into a woooden bottom.
