Already breeding, but not enough...

One other thing I thought of, when you pull out females, and she has a small litter (< 9) put a mark on her tail when she weans. This way when she has a second litter, and it is still small, you know she is a poor producer because of the mark on her tail from the last go around. Could work!

(20x6)-30(5 grow out racks)= 90

remember, the grow out racks double as an out going quarantine area...

so I get litters out of them sometimes also.

Nice, I love it! Never thought about permanent markers! Now even I could keep track of that. How about a mark at the base of the tail for a good litter and a mark close to the tip for a bad one. Females in the system with no marks at all have never produced.:cool:

Thats right there is a perfect idea :gj:

Marker will eventually come off, but I've used it before. Seems like it stays almost two weeks, so remarking once a week is a good idea.

I dont know how well a mark on the tip would stay, try going close to the base. Vertical stripe good, horizontal bad?

There it is!:gj:
