Once they reach maturity, their size will be maintained with proper care. But, growth rates will take a decline and balance out as they near maturity, and they will only grow a couple of inches every few months until they reach their growth limitations. Similarly to humans, milks experience growth spurts when they are babies and adolescents. Milk snakes grow rapidly in the first stages of their lives, particularly during the first few months.

However, some milk snakes can measure around 12 inches in length when they are hatchlings, depending on the subspecies and genetic factors. When milk snakes are born, they typically measure around 6 inches long. How Long Does It Take For Milk Snakes To Grow? Thus, a large and healthy milk snake would likely give birth to hatchlings with a higher probability of growing to larger sizes. Generally, the offspring’s growth potential will be affected by the size of the parents. Other than the influence that the subspecies of milk snake will have on size, genetics play a rather large influential role.

The predominant factor concerns their genetic traits. Generally speaking, male milk snakes can grow slightly larger than females, but they are typically within the same size ranges since they are alike concerning physical features and sexual aspects. It’s been reported that within the United States and Canada, milk snakes living in captivity grow to around 51 inches. Milk snakes can measure between 14 and 69 inches or between 3 and 5 feet in length, but some milk snake subspecies grow around 7 feet in length. Read our Milk Snake Care Sheet (Complete Guide) How Big Are Milk Snakes? I never successfully bred them (they were much more interested in eating each other).Ī rich girl in a neighboring state saw pictures I had posted on MySpace (remember that one?) illustrating the rainbow iridescence scatter they have in the sunlight: she thought it was quite impressive and made me a very generous cash offer for the breeding pair.Everything you need to know about caring for Milk Snakes in captivity: I think the tanks were a bit 'snug': unlike ball pythons they were more active and needed the space.

I was keeping each of the adults in a 40 gallon breeder tank at the time 36 x 18 x 16. Twice frozen rodents that my ball pythons wouldn't even consider.whatever-sure, toss them in: they will eat them. They ate pretty much any food item regardless of condition. They grew to an impressive 6 feet relatively fast. I used them as 'garbage disposal' for uneaten f/t rodents for other species I kept at the time. Mine HATED water, they would not soak and so I had to mist them on a daily basis to prevent shedding issues/retained eye caps. I had a pair of black milksnakes for years.
