I have the four animals involved in this project quarantined together. They are all animals that have arrived in the last two months. I do not know how everyone else quarantines however I bring in new animals over the summer and they get quarantined together. There are only so many rooms and so many racks. I usually start in november but this boy was breeding before he came here and has already been off food for sometime. I deemed it acceptable risk and appropriate to breed him now and then get him back on food. I am quite sure that there are others that have rolled the dice in a similar fashion.
