It is raining like stink (10-20-30 mm today) and the winds are gusting to 60 km. Chance of a thunderstorm. From the forecast it sounds like the T-storm and the gusty winds are just for this morning, but maybe I'm being too optimistic.
As for thermoregulating, they should be able to do that by Monday-Tuesday. However, Trey and Princess will probably try to keep them covered in this kind of weather until such time as they really can't fit under them anymore. Wet chick = unhappy chick = physically stressed chick.
I have never wanted chicks to grow quickly, always lots of things to do and love to watch them grow. This year however, I have had to catch myself a couple of times from saying "I can't wait until you " umph *slaps hand over mouth*. Am not going to say it, am not going to say it!
