For a good month, our silkie was laying eggs, and all have been infertile. Since last week, she's been broody. She sat on her eggs for a week. She's laying maybe one egg every other day. She now has three. She will not nip at us, only at the other chickens who ever gets on her last nurve. While my husband and I cleaned the cage, she decided to get up and take a break. She ate, drank, and ran around. I checked on her eggs while she was away and saw TWO eggs with veins in them! WOOHOO! She recently laid an egg yesterday, so I didn't see much in that one, but I'll take two good eggs any day! I'm so proud of her!
I'd say maybe 6 days
