If you've got great neighbors then your half way there. Depending on your location predators could be an issue but if your penning up at night you should be ok. Keep this in consideration, age will play a huge role in personality especially in young males that have bonded with humans, in my experience young male peas especially blues can be "bottle babies" meaning they kinda lose their fear towards humans and during the season they may attack you this is why having good neighbors is a must, if they have sliding glass doors, french doors, etc... This includes rims on cars pretty much anything they can see their reflection in, will be attacked and can cause damage to both. India blues do free range very well but once they get a "bad" habit, it can be hard to break, this includes neighbors who feed cats or dogs outside as peas will wait on a daily and attack what it can for that food not to mention pea poo is a terrible smell to those not used to it. My neighbors as do I feed our outside 4 leggers at night. I know, long winded but, I hope it helps and please keep us posted.
