Hi and Welcome to the Forum.
Do you have the space and resources to handle TWO bulldozer tortoises? Most ppl have their hands full with one...at this age, you should be soaking daily.
Way too early to determine the sex....
I have a large backyard. It’s two levels and the only promblem I have is that the large space is up stairs. How long do I keep them inside before I move them outside. They are about 4wks old now.
