thanks for replying, I will try and post some photos soon, One of pair consits of a albino female and violet male, The female cere is does not appear to be in breeding seasonbut the male is dark blue. two of my other females and their mates are dark brown ceres, and the males dark blue. All but one pair appear to preen, one female rips at the paper, but no females have settled into the next box, i have no mice and their is always loud chatter amoungest them. I have swictched pairs and taken nests in and out and then back in. One pair is breeding great and have four babies, but others havent. Been in there for more than two months?
