Usually around the 12 week mark you can start conditioning them.. can't really tell the age of yours by their picture but they look like they are old enough.
I would condition them for a couple of weeks before you do attempt- they do not look ready to be bred at this point but in a few weeks with proper conditioning they should be fine.
The female in my avatar is just over 3 months, and is in the process of being conditioned for breeding in a couple of weeks. She is approx 1.12 inches give or take some (don't have ruler near me and she is moving too much atm to be helpful lol)
