Re: Honduran Milk snake size?
To begin with, are you sure that it is actually a Honduran Milk snake and not one of the other species that do not grow as large. Assuming that it is a Honduran, there are two factors that usually dictate the adult size of pretty much any animal, including snakes. They are in order of importance, genetics and availability of quality food and living conditions. Also, there is significant variation in the size of milk snakes; Honduran Milk Snakes in particular. I believe that at least some of this variation is due to the amount of cross breeding between species of Milksnakes in the past; some intentional, some not. If for example, you cross a Honduran with a Nelsons milk snake, you would not necessarily be able to see visual differences very easily unless you went to the level of counting scales etc, and the coloration of many of the morphs are so similar, it would be difficult to tell by coloration. Even if your snake is a pure Honduran, there are differences in size just like there is in any animal or people for that matter. My first Honduran was born in late 2012, she now weighs about 1350 grams and is between 5-6 feet long. When she was small, I fed her (multi-prey item meals) which means I fed her two smaller mice rather than one large mouse at a feeding. I felt (no scientific evidence here) that the smaller prey items were easier to digest and absorb and she was ready to eat again sooner than if I fed one larger prey item. As she started to reach her full size, I switched over to larger single prey meals. I may be all wrong here, but she grew quickly and has attained a good size for her age. To answer your question, by five years old, a Honduran Milk snake should be pretty close to as large as it is going to get.
It's sort of like the answer Abe Lincoln gave to asked "How long ought a man's legs to be?", to which he replied, "Long enough to reach the ground." Your snake will be as long as it is supposed to be.
