Hi there, and welcome to the forum! To answer your question: torts are just like people in this case; each one's different. Some couples will have instant success right off the bat, while others can struggle. Just be patient. In case you haven't seen it already, here's a great page explaining the whole process of breeding Russian Torts, and how to deal with it from the first squeal (see attached pic ) to the first peek of a beak breaking through the egg. Good luck!
