Our Easter Egger has been laying eggs with a strange discoloration/texture on the blunt ends for several weeks. The egg quality seems normal, I just wonder if she's lacking a nutrient or something. Her behavior is also normal. She seems fine, just wanted to make sure she's getting everything she needs. (We feed lay crumbles, a small amount of scratch, and assorted garden and kitchen scraps, and of course she eats whatever insects she can get a hold of.)
Some chickens lay eggs with the same deformities every time, since so many have been the same it might just be normal for her.
Her diet looks like it could be deficient in protein, the scratch and veggies can dilute the already minimal protein in a 16% layer feed. But that probably doesn't have anything to do with these egg oddities, which looks like it could be a shell gland malfunction...or it could be a lack of calcium. I would provide oysters shells in a separate container available at all times, the layer feed probably has enough calcium but sometimes some birds need a little more, see if after a week or so that helps at all.
I do agree with all the suggestions above. But I will add my two feathers in anyway. You might want to try giving them only their layer and oyster/extra calcium product first thing in morning, so they eat what is needed for good egg production. Then later in the day allow scratch & some veggies to end the day as a treat. They will finish off grabbing some Layer before roosting. They are just like us, and rather over eat the treats, which dilutes the nutritional needs that are in the layer & oyster. You didn't mention age of your Ladies; that could be a factor as well.
