Thank you! I was told that by the breeder. However, if the bloom is invisible how can it affect the colour of the egg?
It seems to have a slightly milky tint to it, so I think that's how it can affect color.
If eggs have a really heavy or tacky bloom they can even stick to the hen's butt until it dries enough to fall off.
..or 'glue' nest bedding to the egg.
Feels like runny mucus.
