I am a newbe and have 4 hens. The first started to lay about 2 weeks ago and has one a day and the eggs look great. The second had one 6 days ago. It had just a little blood on the shell. She skipped a day, than another one that was fine. After a day off, she laid another one today. This one had blood on the outside again. Not a whole lot but enough to see it. Does this sometimes happen or should i be concerned. Thanks for any help
