I am getting an egg with soft shell, free choice oyster is available, feed Folk raiser, have recently added Layanna to a couple feeders. I think the soft shell may be from my Orpington. She went broody and hatched 6 chicks that are now about 10 weeks.does it take a while for the hen to build up enough calcium after she returns to laying? I have 2 more hens with 6 chicks, so I keep the flock raiser in their coop area but all free range and have access to all feeders. the broken eggs started to show up when she started laying again.
