Adding to the Flock+Heat=Stress?

[pollo curioso]

I've been preparing to add about 4 hens to my flock but I'm concerned that with the extreme heat forecast for this week (107 today!) all the girls might become stressed out. Is this something I should be concerned about? The new hens will be in quarantine in the corner of my barn- out of the sun- but it's still about 102 in there at the peak of the day. My other hens free range all day and often hang out in the barn stay cool. They'll likely see the new arrivals.
Any thoughts?

Not sure where you live, but is it expected to stay that hot for a long time? If not, maybe you could wait a couple of weeks, just in case. On the other hand, maybe they will be too busy hiding in the shade to peck each other!

I'm in central Texas. Forecast is for 100+ temps for the next couple of weeks AT LEAST. Summers here generally float around 100 for a couple of months. Doubt its gonna get any cooler...
