Or rather, the chickies' eggs ...
A recent development in hens who have been laying for a couple of years. The whites of some of the eggs are very viscous, even gel-like, cloudy and more white in colour than usual. The yolks are very thick. No way of knowing if it's just one or two hens doing this chronically, or everyone doing it occasionally.
The eggs don't smell bad or anything like that.
Any ideas?
