Hi, I’m a new owner of two 6 weeks old (brother) boars and I am currently unsure if they are playing, fighting or showing their dominance? They are still quite shy as I’ve only had them a week however when they come out both boys or sometimes just one will be making this low growling / grumbling noise and will run around the cage chasing after eachother, they also make this noise when eating or sometimes just when they are hiding in their house? I’m unsure what they are doing and want to make sure both guineas are happy and safe any tips or ideas? Thankyou
