Hello I have some seramas and I want to incubate there eggs and I do not know when to put them on lock down or when they hatch. any help would be great.

Some people say serama eggs hatch early but in my experience they have always hatched on day 21 under a broody hen, no different to any other breed. I would lock them down on day 18 as normal if you are confident your temps have been right until now.

I just hatched four chicks - they're a week and a half old right now - precisely on day 19 using an incubator. The first pipped at the end of day 18, hatched a.m. on day 19, the last of the four hatched that evening.

I hatch a LOT of Serama eggs. I keep my temp at 100.2 and humidity is 55. My Seramas normally hatch on day 19 or 20. About 10 percent hatch on day 21. I have had “1” hatch in the incubator on day 18 (it was fine) so so now put in brooder at 17 1/2 days at 100.2 and 65 for humidity. I did speak with another bteeder hatch at 23 days.

My theory with Seramas is 2 fold. First of all, they are from Malaysia which is hot and humid. Regular incubation standards just don’t cut it. I have experimented with just about every combo and this has worked the best. The second factor is their size. It takes a LOT of energy to hatch. Even to just grow. Think about the tiny mass of a growing Serama in the shell. Yes, the nutritional needs are met by the egg but ANY variation in the environment effects the growing embryos. So I have started the following: temperature and humidity as above, all eggs sit blunt side up inside for 24 hours. Then they are put in my Brisnea at 100.4 and 55 humidity. I DO NOT touch the eggs for 12 days. I do not lift the top unless there is an emergency. At 12 days I candle without removing the egg. Empties are tossed. Everyone goes on lockdown at 17.5 days. They are watched VERY closely. I must say with other breeds I follow the normal routine and handle the eggs a lot! When the first chick hatches it stays in for 24 hours. It’s cries will prompt the other babies to break out. When I open the incubator I take each egg and quickly candle them and divide them in 2. Those who have broken not their air cell and those who have not. I then put each egg where the chick has broken through the air cell and assess it’s cries on a 1-10 scale. If the chick is barely crying I break a safety hole in the middle of the air cell and place it back in. Practice this on duds, as it can shrink wrap a kill the chick very quickly. I don’t ever mess with chicks that haven’t broken through the air or chicks with strong cries (they are all drama queens when hatching)!

I also intervene MUCH more than any other breed. The typical scenario is the chick is incorrectly placed. Usually the chick is unable to turn or unable to push the top of the egg off. I have studied the hatching process thoroughly. The chick must accomplish many things prior to
