Ok Had my male royal for about 10 years now. He is 4 and a half foot and weighed in last year around 3.8kg Im aware he is overweight due to his eating habits which i am in the process of rectifying. For the past 10 years he has been fed nothing but frozen chicks with the odd mouse/hamster thrown in but it was rare he would eat them. He is a consistantly good eater.......with chicks...... He was eating 2-4 per week. (I know i was over feeding and thats resulting in him being overweight) I lost a Royal python in the past due to the snake stopped eating. The vets tried force feeding her but i lost her. So i think this was my way of making sure he didnt go the same way. Anyways.....I decided he could do with better foods to eat other then chicks. If nothing else but for the calcium. But he was VERY bad at eating mice and rats so after looking about the net i decided to try temp him onto other rodents such as gerbils, multimammates and hamsters. After about 3 months of no chicks and me offering a rodent once a week i was loosing hope. I was braining the frozen rodents to help temp him and warming the prey up first but he still didnt seem interested. I was putting this down to the fact he was overweight and wasnt very hungry. BUT alas he started eating! He will now eat multis, hamsters and gerbils! He is currently eating 2 a week. And yesterday he even ate a small mouse! After i brained it and rubbed a multimammate all over it but still! My original plan was to tempt him onto mice and then rats but im not feeling very positive about the outcome. I have found a supplier of large hamsters. They are 70grams + in size and think he would like these. They also breed guinea pigs and they do minis for around 90-150grams. I was thinking of feeding him them plus the odd chick, multi and hopefully mouse/rats in the longrun. My question is should i bother feeding chicks at all and how often should i be feeding him? And what size prey? I was hoping to feed him a large hamster every week but would that be enough for him? More? Im not really sure how much and how often.
