I have two silkies that I got last weekend and they came with a rooster.I am hopeful they go broody,they was broody where they came from.They have five eggs in the nest box the first one has been there for bout five days or so.Im hoping one of the hens goes broody.my question is,why aren’t the hens going broody?is it because of a new environment or not enough eggs in the nesting box?how long should I leave the eggs out there before throwing them out?
