My chicken is a bantam Silkie, when she was younger we believe she had an obstructed crop due to a large hard lump on the side of her chest when she was a chick. She's okay now but she grew up sickly and smaller than the other bantams we have and occasionally has trouble keeping up with them.
However she's been laying eggs without shells. She lays eggs three times a week, and is the third egg like this in the past 6 weeks. So it's not an abnormal egg everytime, however it's fairly frequent.
Do we need to give her supplements and provide her with vitamins or yogurt? Or is this ok for her and we should just leave her be?
