Maybe since it got warm earlier they started breeding. I know if everything's right small birds will raise more than one brood. I know y'all say length of day and that's probably true for the most part, but there's always exceptions. Look for my old thread "Late nest", I found this hen sitting on her eggs in Sept.! Now are you going to tell me she's been there since April because that's when the length of day was just right!? And I know I never see poults during bow season. IMO I can see that they might start a little early. Hell, if we knew everything about them we wouldn't leave the woods scratching our heads most of the time! LOL!!!
