Hi everyone! New to this thread and new to chickens since 9/13. I was just reading over on the Colorado thread that a local DVM from Longmont was speaking at a Colorado Poultry Meeting and opined that organic layer feed is inadequate in calcium.
I'm a raw feeder to my 4 greyhounds since 1997 so I'm especially interested in the Ca

h ration which is so important in raw fed dogs.
Do you guys have any opinion on Nature Smart? According to the label, it contains a min. of 3.7% Ca, max of 4.0%.
The Layena label that I located on here said their Ca content is 3.25% to 4.25%.
Does that sound like a significant enough difference?
I've emailed the Nature Smart people and asked their opinion, too.
I've got 5 young hens and get laying numbers all over the map. Today I actually had an end-cracked egg (like a faint spider web); and day before yesterday I had one of those egg-shaped but now flat soft things that I've seen a few times over the past 6 months. I researched it and found "low calcium" can cause those. These hens were in a 27-bird coop but i always suspected it was one of these 5 as the owner of the 27 bird coop said she'd never seen one before. And here we got one this week; they've been here about a month.
So that's why I was wondering about Calcium content.
