I am the proud new (first time) owner of 15 RIR's and 15 EE's which are all now one week and one day old. All seem to be doing fine, healthy, eating, drinking, growing feathers, etc. However a couple of the RIR's have "pasty butts" I have tried to remove the paste with a wet papertowel but the paste seems more like concrete. The vents do not seem to be blocked but i am concerened that they will be if something is not done. I also however do not want to hurt the little fuzzballs by yanking fuzz from their butts (i know that would upset me something fierce). HELP!
