I have a few chickens and 1 just started laying. I saw another hen of the same breed in the egg box today...SO I was thinking she maybe is also going to start laying....however she has been in the nest box for a few hours now. I am beginning to get concerned. It is pretty hot today and she is panting pretty hard. I removed her from the box and she got a drink and then went right back in to the egg box. Should I be concerned?
