8 out of my 12 hens are laying right now... For the past 2 days I have 2 hens that are laying and one that is not all going in and out of the boxes. Each one of them go in, stay for an hour or two.. Or maybe longer and then they leave. Then the next one goes in and does the same... But no eggs. About to go Broody? Or just off behavior? They are barred rock, production red and light brahma.
