Not Interested and Off Feed

I put the male in for 2 days, if I see a lock during that time I let them finish. Then at least 4 days off, offering a meal. If I dont see any locks in the first 48hs I take him out, and try again next week.

Thanks everyone, I'll take your advice. I'm sure he'll get going eventually:)

The thing you need to know for sure with a male of that size is he producing sperm plugs? Without these you won't have much luck.
