Hi from France,
Madagascarophis colubrinus insularis. I have a group of 7 specimens and this year I have had 2 young from the first 5 eggs. There is a group of this snake in breeding at the University of Texas if my memory is good. It is not easy to start young snakes and force feed must be envisaged. Very few informations about this species. The adult snakes I have take food without lot of problem on mice. You can see picture of young to this link :
