Thats a link I havn't seen yet. Nice one! And I do much searching...
Lobsters are great feeders. To feed them off it's best to be able to sex them. Because you want to feed the males off & leave the females, if you want to keep a colony going.
The males look like this on the under back side near the tip(end) of the abdomen. () The females look like this ( ). Also the females are thicker & rounder on the backsides (like most females...lol). The males are thinner when looking from the side. Males also move faster & are generally more energetic.
Once you get some out in a small container you can cut off thier head(they move around wildly), stick them in the freezer for a couple min(makes them sluggish & slow) or trim thier legs(so they cant climb out of a feeding tray).
Oh, like the article. Keep roaches in any plastic container with a top & some screen on it. I use a door knob-hole driller to put large holes in. Then use a soldering iron & hold the cut screen on the plastic from the inside. The iron will melt the plastic thru onto the screen. Sometimes hit the screen with the iron & it will heat up & melt the plastic. Once done, hot glue the outside edge of the screen & plastic.
Hope this helps. Sorry for the spelling errors didn't have time to check it.
