Good to know. I let 5 broodies set last summer thinking a lot of the babies would get predatored. They mostly survived, so now I'm getting over a doz. eggs a day. Too many for me and my 3 customer friends. I shouldn't compain. I'm going to try freezing some but I had forgotten reading about the oil. I give a lot away to tenants and feed older eggs back to chickens, but a sack of feed a week makes for expensive philanthropic pets.
Everyone has given great advice and as you discovered you will find what works best for you. Everyone's situation is a bit different from the number of birds, coops and breeds. I have 12 coops and currently around 200 birds with another 200 eggs in the incubator. I have poop pits under the roosts that I can rake out from out side of the coops, which helps keep the coops cleaner because they tend to poop a lot while roosting. I do use chicken wire around the perimeter of my pens and welded wire in-between the pens, but I also have electric wire around the pens and coops as well as heavy duty netting covering all of the pens and concrete under the gates to the pens. Everything was done because of at one time or another a predator. I've dealt with coyotes, bobcat, fox, possums, skunks, hawks and owls. I haven't lost a lot of birds to predators but have lost a few over the years and now I'm pretty predator proof. Not long ago I had a predator get a gate open to one of the pens and it killed a couple of birds. Now I put different latches on the gates so nothing can unlatch them. I do have several game cameras in different spots on my property and most nights I see a predator, usually a fox or coyote and once in awhile a coon on at least one of the cameras. Good luck and have fun...
