They are on 16% layer feed and have free access to oyster shell and grit. I also bake a few egg shells ever other day or so and crush and feed back.
thanks everyone for being willing to teach
I’ll preface this with I’m new to chickens. I have 7 chicks from April. Now pullets. 4 Cuckoo Marans and 3 GLW. I believe all are laying. Though one Wyandotte seems to be laying all soft shelled. And perhaps two in one day. Has anyone heard of that.
