Paired my Pastel and Bumble Bee two weeks ago and after 4 days no lock, or at least I didnt catch them. So I separated them, after a feeding and three days rest I was going to pair them back up but the BB went into shed so I postponed. Put them in together again latnight and just went to check on them and they were locked!! This is my first ever lock so I'm pretty excited, also managed to educate myself in the process lol. .... I left the water bowl in the tub with them, the tub was fogged up so I couldnt see in it to check on them without opening it up ..... so when I did they were locked YAY! Right?? Except they started moving around so as gently as i could I closed the rack back up. Hopefully I didnt disturb them enough that they stopped . Note to self ... from now on the water bowl will be removed when I do pairings
