I'm going to be out of town for 4 days. Can I still eat eggs that have been left in the nesting box? Will it make me sick to eat them since they stayed outside for 4 days? What if they are dirty and I have to wash them when I get home. Will they still be good? I don't have anyone to come collect them daily while I'm gone. Should I throw them away? The highs will be about 70 and the low about 50. Thanks for your help!!
