Sorry I am trying to catch up, I was just going through your posts looking for recent pics of your EE and discovered I had missed your whole thread about your chickens problems.
Do you still have 2?
I didnt find anything that said you had lost another one but only see the one in your signiture.
I can't offer much in the way of different breed experience but, of what I have this is how they are so far.
Dominiques: Very friendly to people, can be a little pushy toward other chickens, especially other dominiques.
Australorps, friendly but a little more shy toward people(they do come when I call them and eat out of my hand). Very docile toward other chickens.
EE, you have one but, mine is very friendly and I think everyone seems to say that about them.
Wyandotte: so far liveing up to what ive read about them trying to be domineering, we will see what happens when winnie gets with the big girls. I'm not sure mine is a girl either.
Sorry I can't say anything about egg laying, I'll know in a month or two.
As for heat, we dont have the kind of heat other places do so again, not much help.
Sorry for your losses,
I hope you find some great new chickens.
I'll be lurking around looking for more pics of your EE
