Nina Norman...or is it Christina...I'll admit, I'm confused
That is not an unusual condition though, so we (or I) will move on.
You are off to a good start by the fact that you have started a compost pile in the first place. Add to that, it is working confirmed by the reduction in mass.
Now, to some of your questions. First the ants. Usually the ants I will encounter in my pile are fire ants, but that is when my pile gets a little too dry. You mention it is very wet in the location where you found you ants. I give, how about giving your pile a good and thorough turning. Adding a bit of moisture and turning the pile generally helps to move my ants along.
As for the worms, don't waste the effort or money by attempting to "seed" your pile. I tried several times in an attempt to grow a large worm population (instead of building a dedicated worm bed) and decrease the time needed to break down the pile. My guess is the pile just got too hot for the worms and they moved on.
I assume by eggs, you mean egg shells? I throw mine in without breaking them up, and they stay around for quite a while. Obviously if you rinse, break them up, they will break down much faster. If you will hold some of your kitchen wastes for a couple of days before adding to the pile, the composting will have begun already, and I don't see where a dozen egg shells per week would be too much. On a side note, if you decide to take on vermicomposting, I understand the worms really like some shells mixed in with the rest of their food.
When dealing with a compost pile that is too wet, just add some dry materials and mix. I don't spend a whole lot of time or effort "watering" my compost pile. I add kitchen wastes when I have accumulated several containers worth (Folgers plastic coffee cans or Blue Bunny 1/2 gallon sherbert buckets, or OxyClean 6 lb. buckets - I think you get the picture
). This can occur in three days or a week. When I add these to the pile, I rinse the containers with water and pour into the pile. That is generally the extent of my watering. Year round, I keep my pile covered with straw or dried leaves. This seems to help hold the moisture in. I may or may not throw in some dried molasses or corn meal, depending on how energetic I feel
As far as too much or too little watering, too much or too little turning...I will only refererence one of my favorite bumper stickers (which resides on my refrigerator and not
the bumper)...Compost Happens
In other words, unless you are doing this (composting) for a source of income, or you just want to complete the composting process as quickly as possible, don't sweat it. The process will work with and without you.
