hi friends I was wondering if small white spots on brown eggs a deficiency of some sorts? my pullet just came into lay. her eggs have been beautiful except the last one. it seems to have little white spots on it? I was wondering if anyone knew if this meant she is deficient in something? she's been having a bit of a rough time laying each time she lays she pants with her mouth open. after the egg passes she is fine.I've been giving oyster shells to help her out. as I said the last egg had little white spots on it. is this just how it happened to be pigmented or is this a sign of deficiency? thanks for your help.
