Hi, everyone! I have a smalk flock of 3 hens and 1 rooster. They are all 16 weeks old. About an hour into their outside time, my red sexlink hen went over and laid down next to the waterer and started to dig herself a little spot in the grass. At first, I thought maybe this was just a dustbath. But she has been laying in it and digging a little at a time for about 30 minutes now. She has never one this before. She is in the shade, and the rooster seems to be keeping an eye on her, even digging more around her and grooming her. She hasn't gotten up yet. This is very unusual for her, and I am a first time chicken owner so I'm just a little concerned about everything that happens for the first time. Could this be her lating her first egg? Do I leave her alone or try to put her back in the coop/nest box? Is she sick? Any information would be incredible. Thank you!
