A few of our silkies, possibly all 3 of our naked neck girls started laying, but almost immediately stopped. Their conditions haven't changed, they have plenty of food, water, and heat. But for some reason the girls just stopped. Still waiting on most of the silkies to start... We got 8 eggs, 4 hatched, one died in a brooder malfunction, the other three are happy and healthy. Any ideas on how to encourage egg production to resume? Thanks all!
