Hi! My two year old Red Star has been laying shell less eggs for 5 months about every other day. She seems healthy and unbothered by it and lives with 3 of her “sisters”. Sometimes she lays a really weird looking egg that looks just terrible and she acts very somber and doesn’t move around much before she lays that one but that’s about once a month. Is it ok for her to continue like this? Anything that can be given to her to make her stop laying and just be a happy little backyard free range chicken eating and poopin’ with the rest of them? They’re on a layer feed and get oyster shell for extra calcium since I thought that may be her issue. Help! Thanks! Olivia.
