hi everyone i just needed some advice. i had to separate my 2 boars blood was drawn and they were fighting it was not very nice to see. so we separated them into to hutches there good size hutches 2 tiers and one in each hutch. the hutches are put next to each other so they can still see each other but not hurt each other at the same time, we also have 2 separate play pens so they can still see each other and have new scenery and to play. but they still chew the bars some days they chew the bar constantly some days not so much. i change there set up 2-3 times a week so there not board and they do have toys but there attention spam is low so there not always interested in the toys. i was just wondering is there any more things i can do to help them stop chewing the bars as i know chewing bars is not normal. thank you.
