I recently moved my girls from a huge country lot to a 200 square foot run in town. Since the move, egglaying has been less than 25% of what it normally is. I have 4 altogether, and get maybe an egg a day. Could the stress be contributing? Or perhaps their age? The oldest just recently turned 2...I can't imagine they're past their prime already. One girl may be molting. Is there anything I can do for them? Or do I simply wait it out?
