Strange question I know but.....if the average daytime body temperature for fowls is around 41.5C why do we incubate eggs at 37.5C?

I can see that having a high temperature would probably 'cook' the egg but I didn't realise until recently that a chickens body temp. was so high and they hatch eggs very successfully. :laughing

Is that their internal body temperature? Most likely they don't bring the eggs to the same temperature as their internal temp, much in the same way readings differ when taken internally vs externally in humans. My guess anyway, lol.

I would have thought the same as Azira. The eggs are resting on cool ground in a nest so unless the eggs were completely wrapped up in a wing for 3 weeks they wouldn't get to the 41.5.
I'm sure someone with more knowledge than a guess will chime in though :-)

Most of this is interesting, but not relevant to the question, however, it does say that a chick is hatched with a body temp of 39.7 which increases daily' for about 3 weeks to the adult range 40.6 -41.7 resting/brooding - active

This one compares the effect of eating and says that not eating results in a drop in body temp. It refers to a 'growing chicken' but may be relevant to a non eating broody (as a form of semi hibernation)

Interesting links, Sue. It makes sense, without fuel coming in, metabolism slows, which in turn reduces body temperature. Given the periods of time that broody chickens aren't eating, it might be a combination of a reduction of their body temperatures and the natural difference between internal and external temps that exist regardless.

Interesting question Saltwood, thanks for asking, I hadn't even thought what temps a chicken runs at normally, had no idea it was so high.

Sorry for the delay in answering.

Yes I was surprised to learn their body temp was so high.
Always something new to discover!

mmm thinking about it,
our core body temp is 37 give or take, but i seriously doubt that if we measured the temp of where were were sitting, we would generate the level of heat to the ground if that makes sense

so, although the bird's core body temp is higher, the temp they generate by skin to egg contact is less.............mabye??????
