So the plan was to hatch a few chicks while we had the extra eggs and prepare to replace our layers next spring. Hatching them now means they should start laying in very early spring. We had a broody hen, but she stopped when I tried to move her from the top nest box to a more chick-friendly lower nest box. So time to break out the incubator.
We have a styrofoam hova-bator incubator. It is a still air model. Past hatches have been horrible (both chicken and quail eggs) at less than 50% and an average about 30% have lead me to make changes. First we bought an egg turner since it appeared that opening and closing the incubator to turn eggs three times a day was causing great fluxuations in both temperature and humidity. While it was less work, hatch rates remained dismal. Next it seemed the incubators with a fan were preferred as it insured the heat and humidity were more evenly dispersed. Since our model didn’t have a fan, we could have bought a fan kit. Since I am a computer geek, the many computer case fans I had laying around looked exactly like the ones in the kit. I rigged one up and presto circulated air incubator, but again no real change in hatches.
This time I did yet another internet search for ways to improve hatch rates with piss-poor incubators. This is when I found a forum post about the “dry incubation method“. It was worth a try since fully formed I hatched chicks described our problem. Hoping for at least 10-15 chicks (allows for 50/50 pullets to cockerels) we collected 36 eggs over the course of seven days. One other thing we learned was that the eggs need to be turned during this time of waiting to set in the incubator.
We removed the two red plugs per the article and used a room humidifier from when the kids were young which kept the humidity inside the incubator around 35% without adding any water inside. In the past with water inside it stayed above 60%. Fast forward 18 days, the turner was removed and a small amount of water added to boost humidity to around 70%. The next day I heard chirping and saw a little egg movement. Day 20 we added back one of the red plugs and waited. By the end of the day at least two had hatched. Then on the morning of the 21st day. The windows were fogged over, the humidity was at 90% and there were definitely more than two chicks. The article said DONT open the incubator, okay we couldn’t take it any more. 30 out of 36 hatched right on schedule!!!! What are we gonna do with 30 chickens???
That is our best hatch ever! Could be luck, could be the dry hatch method. If the Beautiful Wife ever allows me to hatch chicks again, we will see if the method made the difference.
What are your hatch rates? What things have you found help increase hatch rates? Share your thoughts in the comments.
