I have three two month old hens (I hope). I was outside this morning watching them after I let them out of the coop. I notice that they like to stretch their wings and run around the coop. However, this morning I noticed that two of them will run around the run, meet in the middle and "chest bump" each other (like athletes after scoring). Or rather more to the point they come at each other like two fighting chickens would...wings flapping, feet extended, and hackles raised. Do hens have hackles? I hope so....I don't want/can't have roosters.
