I must have posted a reply to another question about soft eggs, in case you are interested in seeing what an egg without a shell looks like, check this out: Youtube
We got a few like that, most were broken before we found them. Don't know which hen lays them.
We also get a double-yolker...
I have 2 Polish Roosters. They do seem nap more than other chickens.
Our golden recently had what appeared to be a seizure- he fell over, turned upside down and spun around on his back a few times and then passed out.
I immediately picked him up and he was limp. I carried him by his foot out...
I posted one that I got on YouTube if you are curious what they look like: http://www.youtube.com/watch?v=DO2e4HLKM1w
I don't know which of my chickens layed it, but I do have a Barred Rock in my flock.
