I had an albino burm 10 years ago.. I loved her.. I wasnt home enough (traveling profession) so i sold her to my buddies wife. she was 12ft when i sold her at 3 years old. She is around 19 ft now..
Defenitely get a locking lid.. she was an escape artist, weighted top or not.. they are strong even as babies..and your right no fear at all..
Good luck with your breeding for food project..luckily my friend was a chicken farmer at the time so i was feeding her 5 lb. chickens every 10 to 14 days. Ole Frank Purdue wouldnt be too happy. if i didnt get them for free, they would have cost me a fortune trying to fill her endless apetite..
