I've got a 3000gm+ normal that I have had for two years. She is probably 8-10 years old. She did not go last year and this year she slugged out - 10 slugs and 1 little boob egg that is about 30 days in the incubator. She locked up with 2 males multiple times.

I think I know what her problem is though - She needs to go in a bigger tub. She came to me in a 32qt rack and I haven't bought a bigger rack yet. (bad mom!!) I'll fix that this summer and hopefully I will have better luck with her next session.
