They are pretty sweet! Congratulations Aasagan, seems I'm not the luckiest guy on earth anymore!!

Hope you get as much thrill from them as I'm getting from my own! =)
If you don't mind a few tips from another gargoyle newbie, I had the same eating problem for the first couple of days until I lost patience and put the food right in front of their nose.
I think they were afraid to roam the new enclosure and kept within the same space all day. When I put the food dish mm away from their nose, they started licking it after making sure I wasn't a threat. A couple of days later, they began to search for food on their own.
I began to give them mashed fruit but they wouldn't eat a lot. As soon as I bought baby food, they started feeding much more.
You should ask the breeder what was he feeding them and continue with that diet until you feel they settled in.
As for that breeding pair, I would separate them also. If the female just had laid eggs, she must be tired and the male just wants to keep going! That would be fine if they didn't had the extra stress of traveling + new enclosure and surroundings.
In fact, maybe you should house the females together in that nice terrarium portrayed and keep the male apart.
But anyway, the best option is to contact the breeder and ask for some advice. He knows those animals well, I suppose!
Good luck! =)
