Cody is very right and I am sure people were expecting me to respond to this post. I feel qualified lol. I would say that the eeding on a mouse was a fluke. Does not happen regularly with young greens. I have some occasions where my green will take a scented rodent and then refuse. She actually was refusing ft chicks for a while after the first one she ate. They have a metabolism where they can be picky so you have plenty of time to figure out what they like and how you can get them to what you want. Mine actually took garter snakes as her first few meals. I do not recomend this and I am sure young iguanas would be taken as well. I would deffinitely try ft or live chicks and I am sure your green will not refuse. Do this for a few feeding and then start trying to make the switch by offering scented or maybe you will be lucky and not have to go through the long work and he will just switch without trouble. But most need to grow a little before they take rodents. I had to actually make the switch from snakes to chicks by feeding grocery store chicken parts cut in appropriate sizes. Then i tied ft rodents to the ft chicks and that worked well as long as you tie it tight. You could try scneting rodents with chicken broth or wrapping in chicken skin but this never worked for me. Rubbing a ft chick all over a large mouse or small rat works most of the time for me now. And yes, i am still in the process of making the switch to unscented food. Good luck and let me know what works out. Also, I started documenting the circumstances in which she took food (ex. by hand, left in cage, teasing, tongs, lights on/off, in water, in hide..you get the point) i found grocery store chicken was taken easily in many ways but held still by bare hand with lights off in shallow water worked best. low light with teasing by hand in shallow water worked best for ft chicks and scented rodents. just what worked for me...let me know how your snake behaves.
