I have two gliders that were sick and have been separated from the rest of their family; one about four weeks and the other about 3 weeks. The other day I was getting ChubChub out of his cage to give medicine and his little Houdini self got away from my hands. He began climbing down the cage under his, which has his brother and dad/his original home. The brother and dad were on the inside of the cage, but as ChubChub started to climb down it, the brother started barking, grabbing him, and biting him. I was able to get him away very quickly but I am very worried about putting either of them back in there. Any advice on this, or should I just keep them separated from the brother and dad?

I was afraid of this being the case. I will just keep the sick ones separated for now and maybe in the future put the sick ones in a cage together. I will not being taking any sort of chance in putting the sick/previously sick ones back with their brother and dad. That's so sad, but I will do what I can to protect them and keep them well!:(
Thank you for the advice!
