1 If an object scratches the surface of one of your corneas or penetrates a cornea, keratitis without an infection may result. 2  In addition, an injury may allow bacteria or fungi to gain access to the cornea through the damaged surface, causing infectious keratitis.
Backyard egg is on the left, store bought is on the right. When cooked to over-medium, the store bought egg (left) spreads out much more than the backyard egg (right). The store bought egg (left) has a yolk that collapses when cut.The yolk texture is simultaneously a bit chalky and sticky.The backyard egg (right) has a yolk that holds its shape very well.his was an interesting comparison. The store bought eggs were fresh and of excellent quality, from a local medium-scale producer that does a consistently great job delivering humane eggs at a good price point. I would happily buy and eat these eggs if I did not keep chickens.
When you buy eggs from a supermarket there is a pretty good chance your eggs have been in that carton for almost a month. Commercial egg farmers have 30 days once their eggs are packed in a carton to sell them.If the carton is labeled with a use by date that date is 45 days from the when the eggs were packaged.he eggs I boiled when I made this ible were all less than 12 hours old, and they peeled so easily. It took me awhile to figure out how to do it. For the longest time I was hiding eggs in the back of the fridge for 2 weeks just to make hard boiled eggs.
