Wow are you sure these animals are a year old? I just realized the hatch dates are 2014. I have had one bp that came in at 98g. She is now pushing 350g and i have had her for 4 months. That is acutally a bit slow as she went off feed a few meals. I am pretty sure your prey size is way off.
For the female i would feed 30g every 5-7 days. Some people do 4.
The male 40g on the same feed schedule.
I personally wouldn't double if your rats are that size as too large a meal could put them off feed also. Just feed more often and they will grow like weeds.![]()
