how long is too long to be off of a nest. I came home and momma had been on a different nest. How long is too long? Are they still good? Do you think they died?She has been off for at least 3-4 hours. They were not warm to the touch. Maybe 5 hours at the most. I left home this morning around 8 she probably got off around 10-11. That’s when she got off on Saturday. I came home around 3 and that when I moved her.
