My RIR has been successfully laying for about 1 wk, almost daily - today no egg but she is not acting right. She is lethargic, laying down alot, holding her back end feather up and just not herself. I suspect she has a stuck egg? They are free roaming, eat better than I do, so I don't think it is diet or exercise. I am thinking to put her in the coop with the lamp on to heat her up for a couple hours (with plenty of water) - good idea? Any advice - VERY appreciated!!!
