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.
Hi 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.ost new chicken-keepers wonder at what age a chick can be given treats, but there is no specific age at which it is appropriate. Chicks are tiny and treats will replace a percentage of the nutrition in starter ration that their rapidly-growing bodies require.
