Hello,i have 2 1 month old new zealand babies,and i've decided to make them outdoor rabbits.They will have access to a large fenced in yard all day but i need to give them a secure hutch for night time.So i was wondering what size hutch would be good for them? Also for now they are in the house in the air conditioning.What is the best way to get them used to the heat before they go out perminately so i dont hurt them?Thanks for any advice..
