Today I added a 6'x10' dog kennel to one end of my 'a' frame coop for the chickens to have a little more room to run. This is the first time they have been out since I got them about 3 weeks ago. I'm not sure how old they are, but I'm guessing 15-17 weeks. I have posted pix of them on here before and everyone agreed that 3 are hens, one is a roo. Well, when I let them out today they got all excited. 2 of the hens were stretching their necks out, ruffling their feathers and kind of fighting around like a rooster would do....? Do hens do this, or do I need to reevaluate my chickens genders? oh yea, The one that I think is a roo got so excited about his new space he tried crowing.... it actually sounded like something that would come from a crow, but it was funny to see him get all cocky!
