Well I have an early 08 CH female that if she keeps eating like she is will pass the 1000g mark easily by the end of the year. I still wouldn't be comfortable breeding her A) because she is my first BP and has a soft spot in my heart so I would be devestated if something went wrong and we lost her and B) I just am not in that much of a rush to start. I think based on what I've seen 1500g is a good weight if they are producing follicles. I have a 1650g female that will be breeding this year but she's an 04 and has been bred previously just need to decide which male to throw at her
