One of my silkies has laid a total of 3 eggs in 1 1/2 years.
That’s crazy! What are you feeding her? Hopefully layer with calcium on the side and grit ,
My 3 lay 2-3 eggs a day , go broody for a few days every few weeks. We added a silkies rooster and our egg production increased and broody time dropped,
I think he’s so busy feeding them and chasing them that they have no time to be broody

I love mine more then I thought I would , the eggs are rich and make the most yummy waffles ever
