I put all 8 of my Serama eggs under my broody... I hear they may do better than in an incubator. My hen is a first time broody but she is amazing so far, very dedicated. I am still figuring out the whole incubation business and I have other eggs in my incubator that are due sooner so I hope my broody does a good job. I think she must be the opposite of other hens because she is a pain normally but completely docile when broody. They are on day 10 I believe and I put one other Serama egg under her that is farther along but not sure if it is viable. If it hatches I'll take it away so she can keep sitting. I hear Serama eggs usually hatch at 19 days under a broody and around 21 in an incubator. I recently got a trio of Serama so I hope to have more eggs to experiment with soon.
