I have a small cochin mixed breed that has laid eggs faithfully for the past 9 or 10 months that has become suddenly broody, (sitting in her nest all day/night) but has not laid any eggs for approximately 2 weeks. Should I be concerned that she may be egg-bound? If so, is there something I need to do for her? She is not currently molting, so I don't think that is the problem. Any advice would be greatly appreciated.
