EEs were bred for egg laying Easter Egger... or Americana some hatcherys call them... I have friends here in San Diego County that have Ameraucanas the kind with the muffs under their chin... in low humidity all they need is shade and access to water.
Hi Perchie - yes, too many people are casually calling their EEs "Ameraucana" or "Americana" or "Aracauna" and it gripes me because I paid good money for our APA Blue Wheaten Ameraucana from a private breeder! She was NOT a $7 feed store chick!!! In sharing with other APA Ameraucana owners we found our Ameraucanas seemed more sensitive to heatwaves but fluorished in colder weather where other breeds didn't do as well in the cold.
For what its worth even a pure bred Ameraucana can be called an EE simply because they dont follow the SOP for color.
This is exactly why we paid good money for an APA standard Ameraucana from a certified breeder and have a 2nd Amer on order in a different color standard for this Spring. We didn't want green or pink or tinted or white eggs from EEs but the definite blue of the true APA standard. Someday I may try an EE for fun since my friend loved all her 3 EEs and 1 Amer. Many breeders describe their APA Ameraucana eggs as greenish-blue and not really blue-blue but in comparing our Ameraucana egg color with EE eggs there is definitely a blue to the Amer eggs and the EE eggs have the more greenish-blue. Once in a while an EE will lay a pretty blue without the sage tint but then their wacky feather color gives away the fact that they were never an APA bird.
WE even ran a few days of single digit humidity here.... scary stuff because the flashpoint of the brush is extreme. here on the coast we still have mostly low teens in humidity. At my house Its always about five percent lower than here.
As a kid I lived 10 miles east of Oceanside in SD County in the 1940's. Vista weather was always miserable - coastal cold fog mornings rolling in most of the year with insufferable hot allergy-filled summers. We lived in rural rolling hills that captured the settling fog sometimes until noon while the passes between the hills held onto the summer heat. It wasn't city when we lived there with only one signal in the main town so the area was a gorgeous rural scene where we lived. The only miserable part of it was the climate.
Panting is the only way chickens can cool off that and putting their feet in some coolness. Its normal.... They will also spread their wings out to sluff off some of the heat they will contain. Feathers are pretty good insulation both for heat and for cold. Just keep an eye out for heat stress. Too much panting lethargic.... Feeding green leafy veggies will boost their electrolyte level... Good feed Ice cold watermellon slices are the bomb....
Panting is definitely a way that chickens (and dogs) cool off but there is a point when you know your chickens well enough to know they have reached a distress point. After spending good money on our breeds and since they are more pets than utility we are sensitive to their health issues. I won't go into the details but rest assured we over-protect our hens and go overboard in all their heatwave care beyond the suggestions you listed. For medical care or emergencies our vet is luckily only 10 minutes away! (P.S. Watermelon isn't a favourite with our girls. They will choose and go nuts for cantaloupe over watermelon any day of the week - LOL! I'm kinda glad cause it's easier to clean up sweeter-smelling cantaloupe outdoors rather than watermelon that sours quickly and smells in the heat.)
As always ty for your input. It's reading posts like this I hope will benefit readers - Smiles
