CIDR's

So let me start off with  )) I was thinking it was sunday so I pulled the CIDR's this evening, and gave Lut. Will a CIDR left in for 6 days do anything? I gave GnRH last sunday, and Lut when I pulled them.

Sounds like something I'd do.  This is only my second time using them myself (we pulled them Friday morning), but I've been helping a neighbor who breeds over 300 head a year using cidr's, and he says 6 days is okay - maybe not quite as tight groupings as 7 days, but shouldn't be a problem if you're watching heats.
