I have two adult sows. I just adopted a 6 week old sow. Have had rheir cages close by for 2 days and now have them in a neutral floortime area. I am not sure how I will know when it is safe to put them in their cage together. They have gone back and forth between ignoring eachother, and chasing and rumbling. There have not been any spats but the older girls have harassed her a bit. It started out with her trying to mount them and climbing on them. She is not doing much of that since the first few minutes. Any advice is appreciated.
