My daughter found a HUGE batch of eggs today- 22 in all. They are from different chickens, and there is no way any one hen has been setting on them (the bush is waaaaaay low to the ground, and I keep a head count during the day and haven't noticed any one hen missing for long periods of time- every hen gets locked in the coop at night also). My question, how do we know if they're still edible? I thought I'd read somewhere that you can do a water test and if they sink, then they're safe to eat, but if they hover in the middle or float at the top then they're too old. Is this correct? Can anyone verify this info? Thanks in advance!!
