I've got a layer that has given me two eggs (yesterday and today) with little white egg or crusties on them. Attached is a picture. They are there from when she lays the egg. (I took this mornings right after laying) It is possible to scrap off and the egg looks normal underneath. I looked for parasites (lice/mites) (particularly around the vent) on all 4 but didn't see anything. Although I am new at this but did my searching on here for hints and what to look for. Potential side note, 2 (of 4) chickens don't have any butt feathers (the fuzzy ones) and haven't for 4-6 months I'm guessing from pecking at night. They are 4 different breeds so I know this egg is from this chicken. all 1 year old. They all lay really well and appear healthy. She was in the nesting box for about an hour. It is possible she laid right away and then sat on it for a while. Any idea on what it is? Internal parasite? She is the same chicken that uses the nesting box but (I haven't seen it) takes the egg and moves it to the other part of the coop.
