Hi. Newbie question here. I have a small flock of 6 (2 light bramha, 1 black cochin, 1 speckled sussex, 1 Rhode Island red, and 1 white), We just got our first lay of 6 nice brown eggs. But instead of being in the nesting boxes, they were in depressions in their yard. So this leads me to 2 questions. 1. How can I get them to use the nesting boxes? I have golf balls in there now, but any other tips would be great. 2. How long are eggs good for if they are not put in the fridge for a few days? I think ours were outside for about 2 days, but we live in Colorado and it has been kind of cool here the last week. Thanks in advance for the help!
