MRx our dragons Aethor was recently up high as well even though they were near their food. We had to reset their home and make sure they are within 5 meters to their food. I have that environment thingy out with all my settings in it so after resetting their home I clicked activate on that and they all healed over a few hours. As far as getting eggs nah that shouldn't be a hit or miss. If the Drake has Genos and the girls stats are ready for mating then we should always get an egg. I hope someone is monitoring these questions to answer them clearly and precisely so we have full understanding of how to mate our dragons.
