I am new to chickens this year and just when I think I’ve got the hang of everything one of my olive eggers decides to go broody. I don’t have any roosters nor do I plan to have any roosters. So my questions is what, if any, harm is there just letting her sit on the eggs? She switches between two nesting boxes so I am able to collect the eggs daily pretty much still. I assume she gets up and eats and drinks when she needs to?
