Hey all! First time poster, long time reader here! So I wanted to build a “tree perch” for my little tiel (chip) and I got a branch big enough (olive, not yet disinfected but will be before I give him) and a bucket as a base. I need something to fill the bucket, to keep it sturdy. I wanted to use garden soil but I’ve read it’s very bad. So my plan is to put half of the bucket with soil, and ther rest with disinfected random stones and rocks and then a daily piece of news paper. Will the rocks be toxic? If so, do you have any other free alternatives? I’ve spent so much on toys lately I can’t afford more now. (I obv have enough for the basics like food, but not for more extras)
