That will probably be fine, but you can put a bunch of golf balls in one nest to see if they will go broody, and keep the eggs inside at controlled temperatures (I think its 55-65 deg?) and turn them three times a day. You can keep them up to 10 days without degradation, but after that the hatch-ability of the eggs is less and less each day.Its supposed to get down to 37 tonight. There are 7 silkie eggs in the box. I brought them in because the hens are just laying not broody. Im going to put them back in the morning since they may be laying a clutch. Is that okay?
