Hello. Last year, my geese and ducks were kept separate and they each managed to have their own babies. This year, they all run around together. What happens when they start to lay eggs? Do I separate them again? AND if so, does that mean I should separate the 3 female ducks from each other too? On a different note, I bought oyster shell the other day, because the welsh harlequin breed is known to lay a lot of eggs. I let her go broody and hatch, to give her a rest from laying...........well it is like she is on vacation, because she hasn't laid any eggs since August. Tick Tock. Do you think the oyster shell will help?
