This is a strange question and tale so here it goes. On Friday last week I came home from dialysis sick as can be, my Dad helped me out by giving the flock some fresh water and let them out to free range in my fenced in yard. Dad then went home, but i fell asleep without going out to watch the flock. Now the girls have been left out before with no trouble before but this time I was not so lucky two things went wrong. I came out at dusk to close up the coop and found 4 out of 5 chickens sitting on my picnic table, the wind had closed the coop door. While I was getting them in I was trying to find where the mia hen was. My neighbor from across the street came over and told me that my hen had gotten out and was chased down the street by a fox.(I think a cat) No sign of it anywhere. I got the flock in for the night and that was that til Monday morning. I had an early appointment and was outside to go with Dad and we hear one of the hens crow(?). Dad tells me this is the second time today she did it. She has not laid an egg but is no roo, alpha hen yes. I go to the drs and come back. While waiting for my ride to dialysis I do some yard work while not letting the hens out of the coop/run, no time to free range. I see a gray blur across the street and it moves, then I hear my chicken calling out to the flock. I call her and she comes a running across the street and up the driveway. I get her back in to the yard pick her up and put her back in with the others. She is no worse for wear on being lose for two days. Now you ask whats my questions, 1 why did my hen crow was she calling the other one back and 2 is the wanderer likely to try to do that again or even take more with her? I had to promise my neighbors that if i ended up with a roo and he crowed it was dinner. I dont want to do that to a hen what was just telling another where home is. So any ideas on why or what to do would be helpful.
