Is having sand in the run adequate for the availabilty of grit for chickens? *edited title for clarity*
I'd say not for grown birds. Maybe it'd be okay just for chick grit. They need access to small pebbles/gravel/stones to grind up corn, etc. I've seen mine eat some good size stones at times.
Be careful....there was someone on this forum that her chicken ate too much sand and had to have surgery for an inpacted crop. Vet pulled out lots and lots of sand out of the hen's crop. But there are people here also that have sand floors....
I often wondered about the sandy areas like Wisconsin and Michigan. I am giving some sand to my 6 weeks old black and red sex links.
I'm curious too, since our ground is sandy. There's a little grass growing in the run area, but not much... it's mostly sand. Should I throw down shavings or hay in the run?
