When can my baby eat shellfish? Shellfish can be a healthy part of your child's diet soon after she begins to eat solid food, usually when she's around 4 to 6 months. But if your baby has chronic eczema or a food allergy, talk to the doctor first before giving your baby shellfish.
What kind of oyster shell are you offering? At two years old-they should still be laying-maybe not as much as when they were 1 year, but you should still be getting eggs from them-at least occasionally!! I have one hen who-at one year old-stopped laying completely.It was Christmas time and I had moved one of the roosts in the coop.t two years old-they should still be laying-maybe not as much as when they were 1 year, but you should still be getting eggs from them-at least occasionally!!
