We have 4 Rhode Island Red roos that are 14 weeks old and separated from my yr old hens. At what age do the roos start doing their business? I have a BR hen that has gone broody. Is she broody because of the new roos that are running around outside their run? I'm worried because she won't leave the nest and it gets HOT in that coop. She ate some mashed potatoes that I brought her this evening, but only a couple bites. I'm at work during the day and can't keep an eye on her.
