Tonight when I checked on the chickens, I found a bandicoot in the chook yard. I'm not too worried about him hurting the chickens or anything, but he is digging under the fence and leaving big holes everywhere. There was also a possum in the chook house, who ran out as soon as I went in. I think it was eating their food. Is that all that it will do? or could it attack the chickens too, given a chance? I did try to do a google search and I also looked on here, but I was only finding posts about American possums. As I am in Australia, that advice is useless to me. Any tips to deter them?
