Sorry about that. Basically I have two fixed factors (experimental group and sex) and a random factor (brood). I need the random factor to control for pseudoreplication because I have siblings, which are pseudoreplicates because share genes/environment. however, it is not a nested design. Then I have 8 variables. so I want to compare the covariance structures among groups while controlling for the random factor. I was told that R might do that, I mean a manova with mixed effects.

You don't provide many details, but I suppose that the "brood" effect is nested within the fixed effects, so you don't mean a multivariate approach for a split-plot or a repeated-measures design, but the analysis of a multivariate mixed effects model. Do you? In that case, perhaps the package MCMCglmm may help, although I have never used it, so I can't tell anything for sure.
