Yesterday two of my Degus started fighting badly after free range time. I checked them two hours after they were let out and
noticed Parsley was missing. After searching the cage I found her hiding in one of the tubes, she had a large bite wound on her face.
The wound wasn't deep luckily but there is another problem. After I put her back in the cage thyme one of my other girls started attacking her. Both are behaving aggressively towards another and I am certain its a dominance issue as both are constantly trying to mount one another.
I separated them keeping Parsley with Rosemary in the top of the cage and Thyme with Sage in the bottom hoping they would calm down. Reintroductions this morning were not good as once again they fought, blood was drawn and they had to be separated.
their current cage is 50cm by 80cm by 100cm this is half the size of their previous cage. they are in this cage while I build them a new one which should be finished this weekend however I am worried that this current downsizing has made my Degus less tolerant of each other. I am also wondering whether its because of the time of year as I am sure i read somewhere that the Degu breeding season was around this time. could this be a cause
I not sure what to do right now and don't know whether this behaviour will stop when they are put in the new cage. If they still don't get along I'm not sure i can have two cages in my room permanently
should I introduce them into the new cage together? or should split the new cage and let the live in pairs?
Any advise will be appreciated. Thanks
