Hi I have 2 red eared sliders and I'll have to move with them in a week. How can I transport them safely?
Perhaps in a special crate?
I hope my reply is not too late.

What temperature conditions do you live in and how long is your trip going to be? If it's warm (over 20°C) you could get a special crate for transportation and use it. If it's below 20°C, put several bottles with hot water in there. Although if your trip is long, you'll have to make sure the turtles get enough warmth from them and change the water if necessary. If the temperature outside is below zero, put every turtle in a small fabric bag and transport them in your bosom.
