First of all...I live in N. Texas. We have 80% humidity and 100° temps right now. U have a hen that started laying in March and has been productive every day. She and another hen the same age have lost weight and almost completely stopped laying. I'm assuming the heat. Um going to give electrolilites today. Now 12 days ago I had to worm with Wazine. But, they were fine. But yesterday my hen was just lazy distant. Today she is fine. I change water daily and water down shady areas for them to lay down and cool off. Oh and they are free range. Any suggestions?
