My RIR's are laying now, does anyone know how many crushed egg shells can I give them, or should I give them. I read that you can do crushed egg shells insted of oyster if you want. Is that right?
You sure can, but you'll run out of them more quickly than they eat them, typically. I nuke mine in the microwave for 20 seconds to dry them out, and collect them in a gallon-sized ziploc bag with the top open for air circulation. When the bag is full, I close the top & rollerpin them into small pieces. They like them better than oyster shell!
I'd go ahead & pick up some oyster shell next time you're out & running, though - they'll go through the eggshells fast! I get it in 50# bags at my grain elevator, and it's quite inexpensive. Enjoy!!
