We have 6 Gold Sex Links and 1 Rhode Island Red that are about 21 to 22 weeks old. We're in Oklahoma, so the weather goes back and forth between the 30's and the 60's this time of year, so it's unpredictable at best. Not a single one of them has started laying as far as we can tell. We check the coop daily. We've check all over the yard. Is it unusual for none of them to have laid a single egg yet? Also, we were waiting to unblock the nesting boxes until they started laying. Should we wait or unblock them now? Help????
