Last weekend I was picking out chicks on McMurray Hatchery's website. I picked out 2 hens each of 5 different breeds that looked pretty cool. I proceed to checkout...guess what you have to order at least 25...dang I don't really want 25. So I start looking on craigslist for chicks and someone is selling hatching eggs. Hmmm maybe I will buy a incubator. Research incubators a little, come accross plans for home made incubators. Hey I can make one of those! Find a nice wood box with hinged lid. Sunday head to Lowes, pick up a thermostat, thermometer/humidity meter and some 25W light bulbs. Have the rest of the odds and ends at home. Sunday evening assemble the incubator, hey this thing works pretty good. End up with a 40w bulb on all the time, 25w bulb controlled by t-stat, computer fan with 12v power supply keeps air flowing and eliminates hot spots. Small bowl of water for humidity. By evening temps seem to hold between 99 and 102. Since I have 6 hens and a rooster, who needs to buy hatching eggs? Not me, duh! Why has this never dawned on me before! So 1st egg goes in on Sunday evening 1/2/11. Oh no, in the morning the 'bater has gotten to 108! Time to adjust t-stat. So over the next 5 days I add 8 more eggs, usually 2 a day. Turn twice a day, add water, temps seem pretty stable between 99 and 104 but humidity is usually around 40-45% So that brings me to my question finally Shouldn't some of these eggs hatch? I know that seems like a silly question, but it almost seems like majic or something. I mean the eggs are in a wood box (for got to mention I did put a plexiglass window in it) with a couple of light bulbs and a fan, and one day chicks are going to bust out of the shells? I did forget to mention the hens and rooster are all about 9 months old. They have been laying for about 3 months. So what are the odds that these eggs hatch?
