Pollen in the brood chamber?

[madscientist]

I went looking for eggs this past weekend to see if I could do some splits (the type where you divvy up the frames and rely on one of the boxes to grow a new queen). 
I was surprised to see that most of the brood frames that I pulled out were 80%-plus filled with pollen or honey.  There was very little young brood.  Is this typical for time of year?  Here where I am in TX we're getting to 100 degrees most days and there is no significant flow going on. 
On the other hand, the hives were extremely populous and didn't show any sign of disease or pest.
Should I consider a different kind of split?  I'd rather not buy new queens, but instead propagate the genetics of the queens from my strongest two hives.

If there are eggs and brood in different stages then it doesn't sound like your queenless. They know what they want and need.
