I have a super cute blue mottle Belgian D'uccle - Danger Mouse. She has laid three eggs in two years. But she loves a good egg boast from time to time after sitting on other hens eggs. Has occasionally gone broody - but not for any significant amount of time. I would love her to lay and be able to hatch her own babies.All my other hens lay just fine. Mixed flock - only one other true bantam though who can't lay due to wry tail. Most of flock medium sized - a couple of larger hens too. Any idea what could be up?
