The history of the story is, when you artifically incubate chicken eggs, For the first 18 days you HAVE to rotate them every couple of hours for proper development. Then three days before they hatch you have to put them in what is called "lock down". That is when you do not open the incubator, or rotate the eggs and have to jack up the humidity to over 80%.
Several of us wierdo's who like chickens and hatching our own eggs want to know if a mother hen stops getting off her eggs and stops rotating her eggs. We can not find any studies or information that tells us. So we want to know what the real momma chicken does. I have two hens who are sitting on eggs day 18 will be on Nov. 4th. I want to device something that will let me know if they leave their nest..
Here is some of the idea's I've/We've had on how to do this..
1) putting a sensor mat under the hen. But the only ones I know of alarm when someone applies pressure not removes.
2) Hooking up a light/ motion sensor light switch. Attach a lamp/light running through the sensor that will turn off when the hen leaves the nest.
3) Any other weird miss used device I can think of and haven't applied enough though to yet. I am not above buying parts of something... I don't know if there is any other device that I could put in or under the hen to detect her movement.
I'm calibrating a hygrometer that I will be able to go in the nest to measure humidity. I just really want to try making something like this...
Here is the picture of the girls current accommodations... There is a door that swings shut basically right in their face!
Anyone up for the challenge?
