I have a bunch of RIR pullets that should start laying at the end of this month-beginning of next. Today, I heard EGG SONGS! They grow up so fast! I have 9 trap nests in the coop, but all my birds are free range. It's also a new coop, so everyone is still settling in. Will I need to train them to lay in the nests, or what? If so, how? Thank you!
