My one red sex link was squaking really LOUD while I was doing yard work and getting ready to leave. I had put her and the other 2 in the tractor. So I gave them some snacks and she still kept yakking! So I decided to let them out for 15 mins. Sarah immediately went to the side of the house digging a hole to sit in, then somewhere else. Since I knew I had to go soon, I told then to "go inside" their cue to the coop. She RAN to the coop, dug a hole is trying to make a nest. It's funny. She also pushing hard, I can see her feathers twitching. I think an egg is on it's way! Hopefully she'll be ok so far she gathering little pieces of straw around her while she sits. I just found her sitting on the egg!!! BUT right AFTER she laid the egg, exting the coop, and back into the tractor she made the most LOUD, rhythmic cackling I've ever her her do. Do all hens do this? Is it a "I've got an egg, stay away shout or??? Is this "normal", OMG I hope not! She calmed down after she drank some water and is eating now, just starting preening...
