I went out to feed the chickens this morning to find baby chicks in one of my nesting boxes. Mamma is taking good care of them but do I need to put momma and babies in a seperate pen away from the other chickens? Should I feed the babies and mom lay crumbles or feed the mom and babies starter crumbles? It's now getting down into the 30's at night, should I leave babies and momma outside or bring them in? HELP!!
