I have boiled some excess eggs and planned on crushing them and feeding them to my flock. I've done this before, but since I have so many, it just occured to me: How much of this mixture should I be feeding them? I like to mix the crushed eggs with yogurt and flax seed. They love it. I don't want to overfeed them and I don't want to knock their system "out of balance" if that makes sense. Am I overthinking this??? I have 20 chickens total -- 2 are 8 weeks, 5 are 12 weeks, and the rooster and hens are almost a year old. They all free-range together and obviously the big girls and boy get most of the treats (although sometimes one of the babies gets a hold of a huge hunk of tomato or fruit and runs for their life with the whole gang chasing them!) Thanks!!
