my ballies havent reach their breeding weight but this is the plan...

baby balls till 400 grams - every 5-days. 1-3 mices. target an average increase of 40-80grams per mth.

400 grams till 700 grams - every 5-days, mices + baby rats. (switching to rat phase)

700 grams till 1000 gram - every 7days. 1-2 rats. target a weight increase of 80-120 grams per mth.

1000 grams till 1500 gram - every 7days. 2-rats

1500 grams - every 10-days, 1 and 2 rats alternate week.

Oh, this is the plan on females, males dont need to go 2-rats, as males can be breed below 1500-grams, but im targeting 1200grams on males.
