We had nine hens that are laying, 3 Barred Rocks, 3 Easter Eggers, & 3 Cinnamon Queens that are just about 6 mo old. They all seemed healthy and happy but we went out today and one of the Barred Rocks had died. We are wondering if the heat may of been a factor. We have had a heat advisory in effect for the last week and it was 107 heat index yesterday. Could she have overheated? Has any one else had this happen in instances of extreme heat? The only thing thats that we have fed them besides layer pellets is, grass, bread, tomatoes, sage, and mint. I am pretty sure that these are all safe but if not please let me know! I appreciate any feedback or advise.
