I am still getting about 25 eggs a day from my 60 hens. Currently temps are in the low 20's and my hens are in south facing building where the window facing south is just covered with welded wire. So temp is maybe mid 30's during the day. Question is I have someone that would like some fertile eggs which I have. I have 6 roos to cover teh 60 hens. So what is the min temp to collect and store for a week to cover their order? Or do I have to try and time where they are laying and the eggs are still warm then keep on counter for a week. Or is it just to cold and even though they are fertile or at least should be. It is just to cold to hold eggs to hatch?
