Having said that people in our area lost a bunch of large comb astralorps to heat in the last big heatwave here, but had Aracuana and some walnut comb xbreed do quite well.
Thank you again for the information sjturner79 ....
Just goes to show though, that there is no specific rule about which comb type chicken copes with what, best. ( bad grammar there !! ) . Have heard before ( here and elsewhere ) that Australorps can be a little 'iffy' in the heat - and in general health issues as well. Don't know if that is true or not though.
I am surprised at the number of different comb types. Thought there was about 5 at most.
Underscores my observations about Mindy Araucana and what I see as her heat distress. Have brought her inside on ultra-hot days here in Victoria, to be in the air-con in the family room ( again in the cat carrier ). Glad now that I made the decision to do that. The other two big girls, ( straight combs ) cope well with whatever the weather brings on. Although they do pant a bit on very hot days. I plonk ice in their water to assist that. They become really interested if I drop some ice on the coop floor - - they try to eat it - not a happy endeavour for them, as it slips and slides and they are most confused ....
I spray water onto the leaves of that darned elm tree, to drip down on them ( barring Mindy who is inside by this time ) ... and spray around their coop ( which they do not like much ) .... but at least it keeps them cool. Have a hole dug in the dirt in their run ... which I fill with water on hot days, but all they do is drink the stuff !! .... it's supposed to keep them cool - but no - they'd rather drink it.
Oh well - that's chooks for ya.
