Hello, I'm a first time chicken owner and tonight when I closed the girls up for the night, I notice about four or five hens that were missing feathers on their back near their tail feathers. I googled this and seen that it could be molting or the rooster just doing his job. A little background info on my flock. We have 10 Black Australorp hens and one silver/gray dorking rooster. All of them are about 28 weeks old and I have read that they usually don't moly their first year. Do I need to make rooster dumplings or is this another issue. Looking forward to some expert advice on this. Thanks.
