Thanks Delisha for the suggestion to continue with my "off" FF, but I had already tossed it before I read that. I was worried because it had white-ish slime down in the jar, under the water. I might look up starting the next batch with raw milk kefir. I give them some every morning anyway.
BTW, I wanted to thank everyone for all the good info on this thread. I'm pretty sure it's why my chicks and poults seem to be doing so well. I mostly lurk, but I've read the whole thing and learned a lot! Maybe I'll try to post some pictures one of these days.
