so, while I’m not sure who laid it, it could’ve been Tilly, a black sex-link, Yukon or Miss Prissy, black australorps, or Nelly, a barred rock. They are all 24 weeks old now and have been laying for over a few weeks now. Is this just a ‘glitch’ in the egg making matrix or could it be a precursor to some kind of health issue? This is the first time it’s happened. I’d imagine I should definitely be worried if it happens more than once?
