Found 3 field mice under a tree in my front yard, they look around a week old. Eye's not open and mum is nowhere around. What is the best thing to do?

Call the shelter, they are amazing! I had 5 baby bunnies that I started feeding bc something happened to mom. They released all but one that passed 2 days after bringing them in! Not sure where you live, but it was a good hours drive one way for me! Plus they keep you informed on the progress of the babies!

Drop them off at the shelter. The people there are great and will take great care of them.

I agree.This place is amazing.They have cages for after hour drop off,too.Just use the appropriate size.
