No I don't keep mine in a fridge...there has been proper research done to this with results saying it doesn't make any much difference either way. I don't keep mine is fridge just from 'taking the space' reasons' and if you need some for baking...'warm' eggs whisk easier, so there is no waiting to fridge eggs to come up with temperature.
If you haven't noticed.....eggs are never sold from fridge neither.
