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.
Layer feed should not be fed to chickens younger than 18 weeks unless they have begun egg-laying because it contains calcium that can permanently damage the kidneys, cause kidney stones, reduce lifetime egg production and shorten a bird's lifespan.i Tara. When hens begin eating layer feed (any time after 18 weeks of age) they should be provided with oyster shell free-choice (in a separate dish, not mixed into the feed). It should remain available to them 24/7 so they may eat it when they feel their bodies need it.
