I got five pullets in the summer and they are starting to lay. I know I have one red sex link, two white sussex and then I have two that the farmer said they were mixed breeds?? One of the "mixed breeds" started laying this week and the eggs are a blue green colour...but when I looked on the computer for pictures of chickens that lay these coloured eggs the pictures look nothing like my girls. She looks something like a red sex link but has black tipped feathers around the neck and tail feathers and is a little bigger then my sex link. I don't have a digital camera to take a picture of her. Any one have any idea of what she may be. The farmer had about 50 different breeds of hens all running together with several different roos...so I have no idea who slept with who !! back at the hen house.
