OK, I am going to give everyone here a chance to take potshots at me.
There are pros' and cons' to buying an old snake, I talk from personal experience.
Three years ago I bought two adult snakes, I am talking in the four to five foot category here, a beautiful Okeetee female and an impresive Amel male.
Here's the situation, the female has never given me even one slug never mind eggs, surely a con., the male on the other hand is such an awesome breeder that he covered all my females this season including the Okeetee female, result, three awesome clutches of eggs out of, you guessed it, four females, surely a pro.
Alright start shooting, OH, I dont know the ages of those two snakes I bought three years ago.
