I'm hatching Silkies, and like you, my rooster started going after the hens a few weeks before they laid their first egg. I have 4 hens and 1 roo. We got our first egg about 3 weeks ago. We've been getting 1 or 2 eggs a day. I'm hoping a few of them are fertile!!! Good luck with yours!
Watch the air cells. Silkies often want more humidity.
