These are the eggs we gathered after the first night in their new coop. The only thing I can think of is some reaction to pine shavings??? I live in Florida so it was only in the 70's last night. Anyone ever see this?
We get some every now and then like that too - not with those definitive markings, but the shells feel...dry for lack of a better word. They aren't smooth like the eggs normally are. Perhaps it's caused by stress? Hopefully after they get used to their new place they'll be back to normal. I use pine shavings in my coop so I doubt that's it.
Looks like they are from the same hen... check your hens out and be certain that they are all healthy.
We get them like that also. Many times it is just caused by a temperature differential between the egg and where it is setting. Most of the time you can wash them under warm water and dry them and it will go away. We have eggs do that in the fridge if they are in paper cartons. Not all our eggs but a select few.
Maybe they are like crop circles! LOL Pine naturally has some acidic qualities and if wet can become like lye? you know like lye soap. I don't think it is harmful. All wood has acidic properties. Caroline
