Honduran Milksnakes are great snake and can get to a very nice size, I have own and bred Hondos since 2007 and while I have also work with other colubrids, kingsnakes, hognose, ratsnakes they remain my favorite due to their size and striking colors.
The first 6 moths to a year is really the most difficult when it comes to their behavior, nothing terrible but musking and sometime biting (if restricted) is something pretty typical in young individuals. As they grow that behavior goes away on it's own, usually I don't handle hatchlings until they are at least 6 months old time at which they start to calm down.
Young individuals are very skittish and flighty and will musk every chance they get, once they put on size it's no longer an issue.
When it comes to food, they will eat anything anytime offered, I can switch back ad forth between live or f/t, rat or mice they will eat anytime and when fed F/T I don't even warm up their prey.
