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.
Mash is the smallest, pellets, the largest. Layer feed contains 16-18% protein and has added calcium, which is necessary for eggshell production. Laying hens can be fed layer ration as early as 18 weeks or as late as the arrival of their first egg, but should not be fed to birds younger than 18 weeks old.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.
