I have a RIR that has been setting on a clutch of eggs for almost 18 days. We are getting ready for them to hatch this weekend. My question is: do we let mom keep them warm or should we put them in a brooder? We live in South Georgia and are having HOT temps right now..during the day but nights get down in the 80's. This will be our first time hatching eggs. Just not sure what to do?!
