Don't worry, it is not a dumb question. When I first got started reading Kingsnake was with my first Beardie...it took me months and months to ask the same question that you just asked. so dont worry about it. Any way, the first number is the number of males, the second number the number of females, and the third number is the number of unsexed animals.
So a 1.3.5 would be 1 male, 3 females, and 5 we dont know yets.
Then after the numbers people may say what specifically they have. ie. 1.3 dalmation...would mean 1 m 3 f all dalmation cresties. etc etc etc.
Ask whenever and whatever...it is ok....and welcome to the group. You should post a pic of your lil guy...we all love to see pics. :-D
