Hello Back Yard Chickens, I'm here to ask for some advice before I start a project.

Recently we tried to hatch some fertilised eggs using a broody hen, then two weeks into the hen incubating them, the hen abandoned the eggs, and they died. To solve this, I've decided to start a project which should lead to a working device being made to prevent the death of chicken eggs.

I'm planning on building a very basic incubator like device which can keep chicken eggs warm and alive if they've been abandoned by the hen. If the hen returns to the eggs then the device will turn off and stop heating, but if the hen doesn't return soon then I can collect the eggs from the nesting box to put them in an incubator.

The basics of the design is that it will be a rudimentary pressure plate attached to a small heat source which will fit into a nesting box. When the eggs are in the nesting box and the hen has left them, it will switch on the small heat source. The pressure plate will be a very basic design (to limit potential problems), and I'll make sure it's barely noticeable for the hen, it should look like the wooden base of the nesting box.

One query I have is what heat source to use instead of heat lamps. Heat pads such as those used for lizards could be another option, it seems safer, and would be more compact. Either way, I would make sure no electric components are left uninsulated, or can be reached by chickens.

Do you think that the death of eggs is a serious problem for ‘hobby farmers’?

Can you identify any potential safety issues which might have been have overlooked, and would prevent you from using this product?

Do you have any advice regarding the heat source of the product?

What else would you like to see in this product?


Thank you for any advice! I'll answer any questions about the project if you have them.

One concern is that hens leave the nest every day so you would probably need an hour delay before your heat source kicks on.
Perhaps an alarm would be better to alert you that the hen left the nest.
Rather than a pressure switch, how about a temperature switch that detects a body in the space or a motion sensor that detects her leaving the nest.
 
Thanks for the feedback ChickenCanoe!
Having an hour delay would be very useful, I'll look into how I could do that. I'm not sure about the alarm though, I wouldn't want it built in as it could scare the chickens (maybe if it was an LED outside the nesting box actually... I'll think about incorporating that).

The pressure switch would be the simplest way of building it, and probably a lot cheaper than a motion sensor or heat detecting component.
 
Most of those sensors are close to the same cost. In fact, the pressure switch set to a hen's weight may be the most complicated/costly.

The alarm could be sent to your cell phone rather than out in the coop.
 
Your project sounds pretty complicated. Perhaps your best bet is to use an incubator and not use broody hens unless they're older and experienced.
 
My concern is fire hazard, and also over heating...

Thought of this already, all electrical components will be insulated, and it won't have to be much warmer than a chicken's natural body temperature. I'll make sure to test it before putting it into use.

Just to let you know before I explain my idea, I know there are more sensible ways of hatching chicks, but I like making things and would like to see if this project could successfully keep eggs alive.

May I ask what kind of heating element you plan to use that does not exceed 100° on a full open short if the thermostat fails?

You mentioned heat lamps, they are a known fire hazard in coops...

You also mentioned reptile heating pads, I have yet to see one that doesn't have a big warning to not cover with any type of bedding, if you cover them they have thermal issues, and most are designed for a +20°F boost over ambient temps, thus if the temp is bellow 80° they won't achieve the necessary 100° anyway...

From what I've heard, using a reptile heat mat is extremely unlikely to overheat, I'm not sure what temperature it would reach if it did though, so I'll look into that. Thanks for bringing it to my attention. Also, reptile heating pads are usually placed directly under the terrarium, they have no issue being covered by it that I've ever seen or heard about. I could test what temperature they can keep a nesting box at at some point. Do you have any alternative heating method which could be used?

Heat lamps can be a fire hazard, which is why I'm looking into alternative heat sources, such as reptile heat mats.

Thank you for the criticism, but it would also be nice to receive alternative ways to contract this, as well as rejecting previous ideas. It's very early on in the planning stages right now, and I'm here to get advice from you on how it could work.

I can build a basic pressure plate which connects the circuit after a hen has left it. It's very simple, and I know how to do it. :)
The alarm I'm not sure how to do. That seems quite complex, would you know a cheep way of doing that?
