I’ve become a bit confused after reading about chicken feed and was wondering if someone could help me ! My hens are currently eating Barastoc Darling Downs Layer (http://www.ridley.com.au/products/barastoc/poultry/packaged-layer-range/darling-downs-layer). The issue is, that one of my hens is broody and since she has gone broody, all the other hens have stopped laying too. My question is, if none of them are laying and they are all eating the Barastoc Layer food, will this damage their kidneys as they are eating all this calcium in the feed ? And for winter, if they stop laying for a while, they will still be eating this food. Will this hurt them ? My other question is when the chicks hatch, the mother hen will be eating the chick starter food with anti-coccidial in it. As the mother was vaccinated when she was a chick and didn’t eat medicated food, will it affect her vaccination or should she eat unmedicated food ? Thanks !
