I've been thinking about this a lot. I assume the nest on my place hatched about May 25-27, but it could have been before that. It has been in the mid to upper 40s the last few days in the morning here in Murfreesboro. Other than condensation, I don't think we've had the moisture, but it has worried me that they may take a hit with this cool down.
I actually have seen some poults this year, which is an improvement to years past, but I wonder how many got knocked off, with this cold snap. Hopefully it doesn't affect them too badly.
