I've got 2 bantam cochins that had been laying me eggs everyday for a month or so then I swapped housing and added a different roo in with them and they have quit laying on me for 2 weeks or more now. Is there anything you can do to get them to lay again or is it just going to take time? They are on 16% layer feed now if I upped it to 22% game bird feed and added oyster shell would this help?
