That is exactly how I removed the poop, I tried the wet paper towel but it wasn't really making headway and there was a lot of pulling. So I just turned on some warm water and held her vent under it just a little at a time to wash the poop away.
I have been worried about the temp..their brooder is in the garage and it is warm outside, I turn the lamp off if they seem to be all on the other side of the brooder but how on earth am I suppose to lower the temp by 5 degrees every week? I don't understand this?
