I went out to the coop today, to do some work on it and I noticed that one of the hens were very squawky. She was going in the box, sitting then coming out and squawking some more. Then the rest of the chickens took notice and started following her in there, even the rooster. Every time she left the box, he would look around, to see if she laid an egg. It was a very social event, they all looked like a bunch of midwives. About an hour later she came strutting out of the coop singing proudly.
It seems that their behavior as a group has changed a lot in the past week or so, since they've been laying. We're hearing different types of vocalizations than we've heard in the past and lots of them. They're beginning to sound like the dinosaurs from jurrasic park.
The rooster is acting much different also. He used to hog all the food, now he lets the hens have their share first.
