well i am in MI and we got a frost freeze warning here lastnight ,, i forgot my lil 10 day old babies outside all 13 of them & this morning when i looked at them about 10AM , the sun was shinging right on them & they looked unharmed ,,, ,, so my guess is is u have a frost at night , as long as the sun hits them nice & early they should be ok ,, remember mine are only 10 days old & it got to 32 degreez F lastnight ,.....
