"Natural" Easter eggs?

[Mtnboomer]

For the last week or so I have been finding a strange looking egg in our coop nearly every day. It looks as if blue food coloring had been smeared all over the shell. I checked for any environmental causes and can't find the cause. Can you guys shed some light on what's causing these colored eggs?

Have you been feeding blueberries or similar berries? Have you checked hens vents to see if someone got something going on? It is definitely odd looking.

I give my hens blueberries on a fairly regular basis when it's as hot as the last couple month have been. Never seen that effect!

I've never seen anything like that either. I hope someone who has will comment. Very interesting!

Can you post a few pictures of your coop?
Is there anything wet in it?

Is your hand really large or is that a really small egg?

Also...have you cracked one open yet to see what's on the inside?

I'm wondering if this could possibly be a rotten egg that was hidden somewhere for a long time?

Ooh, that's a scary thought! To the OP: are you finding these in different places in your coop, or in the nesting boxes? Or in the same nest every day, so you know it's a fresh egg? This is a really interesting mystery!

Definitely a fresh egg. They have been in both nesting boxes and on main floor of coop, but I gether eggs every day.

Definitely not rotten. I check daily so i can guarantee that they are fresh
