Today I let the gals out for a few hours. A crow made a loud screech and one of the hens puffed up around the neck. Her feathers stayed fluffed up for about 15 minutes and she would strut around like something was there. The crow was long gone. Is it normal for a hen to do this? Something else I found odd. I have 6 hens. I get six eggs daily except today, I got 8. Why would I get so many? Is this normal. I do have one hen that lays double yolks about every other day. Lastly I have eggs that have spots. It is the first time I have seen spots on the eggs since they started laying 5 weeks ago. I do admit they eat a lot and are getting kind of fat. I keep the feeder full all the time. They are red stars. Thanks.
