ahhhh ok I posted a video of them eating their ff. Man they eat, sleep, eat, sleep what a life of riley they have.It will come off easier with a dab of oil of some kind and the oil will grease the skids for more of the same kind of poops so they don't stick as badly. If you can, through a clump of your soil in the brooder with a little grass intact and see if that doesn't help too. Healthy for them and they can get valuable minerals, bacteria, grit and playtime out of the clump.

Here's the video but there are TWO of them on there and one is really cute because you can see them running back and forth on the video. I have a red light bulb but it's not much wattage so this one will have to do for now unless they start pecking at each other.
