My neighbors free ranged chickens like to visit my property and I found a large bunch of eggs ... I didn't know much about gathering fresh eggs and tossed the first batch I found (close to 30) and then I found another batch (about 15) and I looked up how to tell if an egg is good .. I did the float test all sank on their side and I also cracked one open on a plate and the white looked normal. I don't know how long they were in the nest. The weather has not been hotter than 76 and mostly in the upper 60s - low 70s or cooler. Do you think they are safe to eat?
