Ok. This is crazy. I have 6-30 week old RIR pullets. They have been laying for some time now. The one stopped laying about a week or so ago, and now she is starting to mount a few of my Barred Rock pullets (24 weeks old). we do not have any cockerels in our flock. I know this girl is the most dominant pullet out of all my girls. She does not crow, nor have any spurs or bumps. I am pretty positive she is a pullet, besides the fact she has already layed eggs. I have read some crazy articles that say a pullet can turn into a cockerel. I don't know if that is true or not...but it is crazy seeing her mounting other girls. I am hoping it is just a dominance thing. She doesn't squat for me, but some of my others don't either. She has always been very close with me. In that she hops on my lap, talks, and lays on me while i pet her. Should i be worried? Anyone else have this issue?
