I have a great collection, they are all great feeders...banging down rats regulary. They shed perfectly. Really seems everything is going well...until last year they didnt breed for us. This year we put them 2gether and they went @ it like rabbits, but later than they should have. But they did get the lock up, multiple times. ;0P Snakes after my own heart! he he he. Anyway...my question is.....why? Why did they skip a season? What have I done wrong? Any suggestions would be greatly appreciated. thank you in advance for your input. wendy
