Our Chickens (two) were laying eggs every day in their coop. When we introduced four new members which were about six to seven weeks old the two adults stopped laying eggs in the coop. They found a box outside the house that fit their needs and started laying in there. One has not layed but two eggs since we placed the new members in their coop six weeks ago. Today we found another one of her eggs in the box but this egg was only about the six of a quarter. I understand that when new chickens are introduced, the layers may stop laying for a while. What to do????
