One of my hens has started laying eggs where the shell feels a bit thinner than normal and also the texture is rough not smooth. I think it is Willow who has also been losing some feather in a line from crop down to her tummy. The whites also seem to be more runny than normal.
Is this something to worry about and what could be causing it. She seems well otherwise and eating and drinking normally. Or am I making something out of nothing!
