My silkies are mating out of season. I've not seen an egg out of either of the hens since they got here, does that mean they are not fertile right now? If they are, how long after mating would I see an egg? Should I set up a nest in the duckhouse for them that they can claim as their own so if they do lay they have a spot to go broody in? (my one silky female is the top of the pecking order).
