Smart Feeder - Light sensor values

[umbrella thursday]

I've looked through this forum and found posts about blood spots, however when my husband cracked open one of our girls' eggs this morning for breakfast, it had a normal yolk inside but also quite a bit of blood - I know blood spots are normal but have no idea how big they are supposed to be. This seemed like quite a lot of blood. Should I be worried? Should I be treating my girls for something?

You do occasionally find this and some hens are more prone than others.

Thank you - that makes me feel a bit better. We've had none since, so hoping it was just one of those things.
