Rated 5 out of 5 by Terrie from Very very satisfied I switched this year to Nutrena Oyster Shell as a nutritional supplement for my laying hens. The girls enjoy it mixed into their salad greens. I have also noticed a stronger egg shell and for that I am thankful as my 3 year old grandson likes to help gather and sometimes gentle is not in his vocabulary.
