Here in Texas I am getting ready to embark on my chicken adventure. But alas, it is only June and we are predicted to have a weekend of over 100 degrees, three straight days! If it is this hot already, I don't want to think about the rest of the summer. So I am wondering, how hot is too hot for the birds and what can I do to help them out? I haven't even bought any yet and am curious to see what is recommended for being tolerant to the heat. I would like some dual purpose birds, brown layers with decent meat, good foragers, etc. Thoughts?
