Here are the 20 egg hues in a bag. Notice some of the hues are very close. The 3 greens on row 3, the 2 reds on row 2. With all of them together, one can see the hue difference. Here are the 20 eggs stacked, by hue: hue 3 at top, 98 at bottom. When stacking them, it is really hard to discern the different hues. I initially thought there were 12 hues.... however I was wrong.... there are 20! Here is the link to the eggs by hue count in the realm: http://www.uorenaissance.com/itemdetails/EasterEggs/9B5/2 In my experience in collecting eggs, I've found that a bunny plops somewhere between 10 and 15 eggs. However this year, I followed a bunny that dropped almost 20. So... curiosity caught me! How many eggs does a bunny actually drop - if not disturbed to spawn fluffy. Could it be 20? Is then a bunny is plopped out? Does a bunny plop 1 of every hue, then is plopped out? Perhaps something to investigate....
I've noticed this as well. At first I thought it was plopped out however while it seems the bunny is plopped out, there might be a cool out period OR move the bunny a few screens away. The last part is a theory however when I gathered almost 20, I was moving the bunny A LOT!
