Review on Naturally Free Organic Layer Feed for Chickens and Ducks - Non-GMO, Soy Free, and Corn Free: Scratch and Peck Feeds by Crystal Bryant

To date, maybe 2 months after purchase, the only useful item in this trio has been DE which I sprinkle on my girls dirty bathrooms and chicken coop to keep ticks away. I haven't had any visible mite activity so I'm assuming it's working and I love that it's organic! The oyster shell and sand seem too coarse to be attractive to my hens but they are only 21 weeks old so they might attract attention. They're quite adult, though, so my plan is to just chop up the oyster shell (probably semolina too, but they probably get their fair share of feeding) into smaller pieces and see if that helps. . However, they do have calcium in their diet, so they may not need supplemental calcium. I'll see when they start laying. Unfortunately, I just learned that chickens should not be supplemented with calcium prior to laying eggs due to impaired kidney function and a variety of other health issues. However, I could feel grateful that they don't touch the oyster shell! Again, I'll update this review if I find that girls start swallowing shells or sand as soon as they lay down.
