Calendar/Planner for breeding rats/mice CONSISTENTLY?

[Xorgone]

Hello all! My name is Xorgone, or you can call me Pat.
I own 4 ball pythons, and recently have decided to start breeding my own rats, and even more recently got a few mice!
The rat should be about one week pregnant, and the mice will either A.) Be food next week, or B.) Be baby-makers for my scaled friends.

To my question: I've looked all over and I can't see to find a planner/calendar/sheet-like anything to help me with my breeding project. I Need to know when to introduce females so that by the time their pups have grown into a decent sized snack for my snakes, that there's another litter brewing. If anyone has any ideas/fingers to point me in the right direction, that would be great Thanks

Also I have a 1.0 Normal, 1.0 Pinstripe, 0.1 Lesser, and a 0.1 Spider

You need to introduce a new female each week knowing that the full cycle (breeding, gestation, birthing, nursing) will take 7 weeks for each females at a very minimum.

And plan for them not to work in your favor all the time I started breeding rat 8 months ago i and was trying to have a litter a week born...need less to say I went 4 months with one litter and I had 4 litters this week.... I only breed to supply my hatchlings I buy everything else. IMO I wouldn't breed with just 4 snakes it is really cheap to order in bulk.

I once found a good schedule but I can't find it so I'll try to remember.

Once the female gets pregnant, it takes roughly 3 weeks for her to carry the pregnancy. Then she gives birth and nurses for about 4 weeks (I plan on pulling my feeders at 4 weeks and holdbacks at 5). Now the schedule I saw gave females a break between litters to regain weight and have a much needed rest. It gave them one week, so from start to finish its about 8 weeks. If you are introducing females to males every week, you "should" have a litter a week if you have at least 8-9 females. Of course, animals never read their own manuals so this might not go exactly according to plan.

Is this the schedule that you had in mind, Jay?

I forgot I posted this years ago.

I will explain it a little further.

This is based on rotating males throughout 3 tubs each letting males spend 2 weeks at the time in each tubs.

Now I do things a bit differently, for one no break soon as the rats are weaned the females get back in rotation, I also rotate females rather than males.

I have a male in each of my tubs and each week I add one new female, females are removed and house in maternity tubs when pregnant.
