It's rained so much and so hard that my chicken starter in my big feeder I just bought it all wet. They love it when I make a mash, but I'm guessing this will spoil and need to be dumped out?
There's no knowing how quickly the mold starts and it can kill them without you smelling the mold. I lost several of my flock this way a few weeks ago, thus the enthusiasm.
Please throw it away from where they can get t it, fast, and give them dry food ONLY!
You can wire up or chain a plastic carpet protector or other plastic thing over where a hanging feeder is, thus waterproofing the area, or build a little picnic-shelter type canopy in your yard if they free range.
