I searched all of the Web and this forum to see if I was crazy and found nothing but my chickens seem to love taking a 5 min sunbath ...they find a good spot with sun and lift a wing up and lay on their side ...The first time I saw my girls do this I had a heart attack and thought something was really wrong and ran over ..they immediately got up and was fine ..whew ...I was thinking that maybe with our weather changing that they were trying to get some heat under their wings to warm up a lil ( it's not that cold yet) and trap it for the cooler nights ....I think ..I was wondering if anyone else's chickens do this and if my assumption is correct ..they have plenty of shade and only some sun beams thru the trees so it does seem deliberate
