This morning I had a hen lay a soft egg. I then got some oyster shells for them to eat this morning. Wondering if the oyster shells will be digested fast enough for harder eggs tomorrow or does it take a few days?
I don't know about the experts' knowledge on this, but I have seen that when my chickens receive too many green treats (too many 2 inch grass clippings to eat- they love grass as food), the next day the eggshells aren't as strong.
Greens are supposed to only be maybe 10% of the diet, I have read.
