My mint morphs are so aggressive. they jump at my food and hit their nose so they have nose rot. They hit into everything. how do I fix that. And they only churp when I play a calling sound from my computer Are they still to young to breed? they are very heathy eat like pigs. I have three two churp the other on just stays away I think she is a female. I have had them for about 16-18 months. Any suggestions?
