My 5 SLW's arrived this morning!

They are just adorable!
I added a little yeast last night as it didn't appear things were going great with the mix I started.
This morning, it was 'fluffy/puffy', smelled more fermented. Looked similar to the pics posted earlier in this thread.
I fed a small amount (along with some dry crumbles to entice them and was happy to see they pecked it a bit before I had to speed off to work.
Question:
It seems to me, adding water/braggs/yeast to the chick starter, that the feed soaks up all the water. Adding more water to keep it 'submerged' and stirring it a few times a day just seems to turn it into a slurry.
I added a little more crumbles to it last night, and now this morning it was more the consistancy of oatmeal, as a previous poster mentioned theirs was.
I needed no slotted spoon or draining as there was no water.
Is this right? I have no water remaining to innoculate a new batch of FF. I could understand draining off whole/cracked grains, but the starter seems to soak it all up.
Can I just add more water/feed to leftovers? (I started more than I needed for the 5 chicks, yet on Friday or Saturday my 25 meaties arrive)
Those With Wisdom: please advise!
