I had a random rooster (now named Randall) wander into my yard a few days ago and has "adopted" my flock of hens. He as of yet roosts in the trees by the house, not in the coop with everyone else. Tonight at midnight he started crowing. I've never had a rooster, and thought, what the heck? Then my German Shepherd who was in the house with me went to the slider and started growling and barking at something in the yard. I swear, that rooster saw/sensed that cat/dog or whatever it was and started alerting. I took the dog out and she chased it off. Wow, I'm very impressed with this roo. I hope the lost/found ad I put in Craigslist for him does not get a response! He seems to already be earning his salt around here.
