My yearling red foot has not been very active almost all of the time in her enclosure & I had her for a little over a year now, just days before I expanded the enclosure but most of the layouts was pretty much the same as before except with a 20+ percentage in additional space. Another question is another RF hatchling of undetermined age was temporarily put in my care from a friend & also placed in the same living space but the enclosure is big enough for the both to not see each other or easily come in contact without any barriers, they were taken out for sunlight & to roam but once I witnessed my yearling was sniffing the new addition temporarily in my ward. Was this a hostile behaviour or just getting acquainted with each other? I did not see any attacks by my yearling against the smaller tortoise & he/she did not try to run but remained still. When both are together I was constantly monitoring the situation the whole time & would separate them immediately, the younger tort was eating normally & did not attempt to escape the enclosure or stayed hidden in or out of their enclosure. Both torts ate normally & most of the time just ignored each other, the smaller one is much more active than the other.
