Mine are breeding like rats! I stopped counting at 11. I Finally got smart and separated the boys from girls. Duh. I don't have the heart to cull them. Cute little buggars. I have the two cages separated on either side of the bedroom. It's too funny... some times they "beep" to each other across the room. It's like listening to a tennis match! LOL The males have a little song they sing in the morning. I guess equivialnt to Crowing for a rooster...anyway, it sounds like a miniature army guy playing Revalie. I laugh every day when I get up around 0430. When I turn on the light they get squacking: BEEP, BEEP BEEP BEEP!....(short pause)...Beep! (one guy is a little "Slow" i guess). I know they are saying "Hey! Butthead! Cut out that light!"
