The containers the eggs are in are Ziploc or Glad microwaveable/disposable containers. I can fit three salvator eggs per round container and sometimes 4 in the square ones. Usually though I keep only 3 in those as well.
I use separate containers for several reasons. First, are the practical reasons. I use hovabators. The eggs die if kept out in the open in the hovabator. It was recommended to use separate containers inside the hovabator for the eggs. These containers fit inside the hovabator. I would like to move beyond hovabators, but have not done so yet. The other thing I like about the separate containers is it lets me experiment a bit. I use vermiculite, perlite, verm/perlite mixes. The containers lets me experiment on a small group of eggs without putting the other at risk.
Chubbs does look intimidating and large in that picture. However, the picture is misleading. Chubbs is much smaller than Labyrinth, and Labyrinth could easily kill Chubbs if he wanted to do so. Petrie - the other male iguana - occasionally dominates Chubbs and sends him moving. Until Mr. Green Jeans went in the room, Chubbs was at the bottom of the heirarchy in the room.
What interests me the most is that Mushu is clearly the dominant animal in the room. That does not interest me based on her being female since my female nile, Delta, was clearly the dominant animal among my niles. However, Mushu is much smaller than Labyrinth now. In fact, I cringe when she becomes aggressive towards him because I believe that if he ever decided to fight back, Mushu would be on the losing end of that conflict and I think losing would mean death for her. I sometimes wonder if Labyrinth's submissiveness to her is influenced by his early experience with her when he was smaller than her and she dominated him easily. Maybe he remembers that and fears challenging her now? Maybe he's just a big wuss (I'm not convinced given that he tried killing me yesterday). Maybe it's a disaster in the making one day... who knows. We will see.
Funny story. Back in July 2001 when they sucessfully mated for the first time, Labyrinth was much smaller than Mushu (there might even be a picture of that mating on the website - pics do exist). Mushu became aggressive and was attacking him. Labyrinth has always been wary around people. However, when I went into the room to remove him he literally ran toward me and practically lept into my hands. He was completely submissive to me and did not struggle at all. Mushu, who is not aggressive toward me, came lunging forward and worked very hard to kill Labyrinth even as I carried him out of the room. It was interesting because she clearly distinguished between Labyrinth and me and was going for him but not me. It should be noted that Labyrinth has never again been enthusiastic about being rescued and resists heartily (which sucks for me).
Finally, I do not think Jalepeño punctured the egg. There were no punctures or deflating of the egg. It is possible he rolled it around or roughed it up. It is also quite possible it had nothing to do with Jalepeño and is the result of poor substrate, poor egg, poor health of baby, or my overenthusiasm in looking at the egg. I will never know; I can only wonder out loud. I would also note that this clutch started with 12 and ended with 3 so it was not the healthies of clutches. That was my fault and probably related to insufficient dirt depth compounded by Labyrinth's staying in the room too long. Who knows, I just mention the factors I see as possible.
As for the mixing species, it is something I have done for a long time. Sometimes it has ended in disaster, most often it results in me separating them back out, and sometimes it has worked out fine. I chose the salvators and iguanas based on the probability of not competing for resources. The iguanas almost never go on the floor and the salvators rarely go up high. Salvators are carnivores and the iguanas are herbivores. I figured this seemed like an acceptable mix. In all honesty, Mr. Green Jeans is the uncertain factor in this mix, and the uncertainty is based on the male iguanas' reaction to her not the salvators'.
In the end, I'm having fun with all of them - except that dead/problem egg.
