I noticed with the few chicks that I had hatch that they are rather clumsy when they hatch and kept stumbling into the other eggs rolling them around. I can't imagine this is good for the eggs, but is it really bad? Is there something I can do for the next batch to help that? Any sort of little, unabtrusive egg holders I can use that won't be a problem for the new chick or inhibit the hatching process? Also I noticed the water by day 21 was kind of scummy. Is there something I can do to prevent that? Am I supposed to try and change the water during the incubation process?
