I do believe that my RIR is going broody as well. She's about a year and a half old Production Red. I got her from Rural King Spring 2014. Up until now, she's been my main layer. But for the last 2 days, she's been hogging the nest and growling at me. This morning she was on the nest but did leave it to eat and drink and explore a little (we free range). But now she refuses to allow me to collect eggs and growls at me if I reach toward her. One plus though, she allows me to pet her now.
