Our summers in SE Louisiana are terribly brutal. We almost never reach 100 degrees but, stay in the mid-to-high 90's from June through September! I was told that the Silver Penciled Rocks would be able to handle our climate well. Is this actually so? However, I was wondering if the bigole Jersey Giants would do well during our sweltering heat and humidity? I've read here in some posts, that some chickens quit laying when it gets really hot. Do either of these breeds tend to quit laying under hot summer conditions?
