This morning when i uncovered the tiels i found all three of them asleep on the highest perch, close together!!

Usually Gracie sleeps on her own somewhere else in the cage, but she had wriggled in between the other two.
From this i have to come to one of two conclusions:
a) they actually all like each other and wanted to be close
b) Gracie got sick of watching Cookie and Bailee smooching so she plonked herself in the middle so she could get a good nights sleep
:rofl:
