i have 14 all together, i offer them all food the same time every week(5-7days babies, 7-10days sub adults/adults) if they eat they eat, as of right now all my 08's and 07's are eating might miss a feed or two but they are right back at it the next time, my big female(2000grams) hasnt eaten since the end of November but she just ovulated my other big female hasnt eaten since mid december but she is also breeding, and my two proven males have eaten maybe once or twice since december, i have heard of a case where a ball python went off of eating for 22 months which is almost 2 years and she was healthy and is still alive today, its not an issue if they arn't eating its only an issue if they arn't eating and they are losing weight, if your snakes are losing weight then i would worry about it

good luck with all the breeding everyone!
