Build a farm. This is, ideally, at least 4 poles high with a small platform big enough for 2 but open enough the baby Lox will fall off. At the bottom dig a large hole (big enough to hold as many as you want). The reason to keep them high up is that they won't breed if there are more than 5 of them in close proximity. You need only feed the 2 on the platform. I believe there is a YouTube video which shows how to build it. Happy Lox pie.
