I started out strong as soon as the confettis were available to buy with menagerie dollars - I got 4 (I had a LOT of boxes). At first over a couple months I had somewhat decent results, some cocoberrys and then 3 plums. I traded a plum for a cherry berry with a friend and eventually was breeding 1 cocoberry, 2 plums and the cherry together (all furs showing). This is when things went south. My first plum (age 205 now) gave me 1 cocoberry and 12 gens when mating a shown confetti fur to shown fur. My second plum (age 178) gave me 15 gens, still mating shown furs together. I think this little stinker was the one that caused me to stop breeding Confettis. My friends Cherry Berry gave me 12 gens (mixing breeding with plum and coco berries). My original 4 cocoberries are 246 days old now.
I still subscribe to the Confetti group in case there is something I have missed with breeding technique, and have 1 cocoberry box just in case I change my mind
I actually had better results with the cocoberries that were true starters straight out of menagerie, fetti furs that were bred out just didn't want to cough up any more goodies for me. I hope others are having better success with these!
