Thank you all for your informative answers, i really appreciate all of them!
I come from Greece and where i will put the chickens can be as hot as 39 celsius under shadow at summer and as cold as -13 at winter.
I want birds that
1-can tolerate those temperatures provided a shed.
2-forage in a fenced area so the cost of their feed will diminish.
3-brood averagely and be good mothers so they can replace themselves naturally without me using incubators.
4-the roosters not be very aggressive at people.
5-and on top of all that they must be good egg layers.
I know that there might not be one breed that fits all that criteria perfectly that s why i ask for advice.
I was thinking maybe to crossbreed some araucanas with dominiques to create my own Easter eggers.
I will research every one of your suggestions though, and take a thoroughly look at the list of all the chicken breeds.
Thanks again and please keep posting suggestions.
