I posted here before in the mistaken belief my female yellow was pregnant.......She really was swollen for many months......You live and learn. I only left the male in for 3 days last year. Probably mistake number 1. Also now, I`m timing his heat lamp off at night. He`s fasted since end of Sept already and he`s leaving plugs and deposits around his cage, though he`s done this in the past with 24hr heat. I give `Cher` as many rabbits as she`ll take before next shed and introduce them after she sheds, and leave him in for much longer. Sound like a plan?
