My 6 laying hens have suddenly stopped laying. After doing a google search and reading many posts here I see that it can be due to worms or heat. None are moulting and none seem sickly so those are my best guesses. I don't think they are eating eggs cause I put a few duck eggs in with them and they remained safe and there are no egg shells to be found. I live in Florida. The heat is nasty here and unavoidable.... Can I do anything to help with the heat? They have a great supply of fresh water, a roof on their cage for shade and we don't feed corn after February since it can cause overheating. Besides giving som watermelon and cool fruits now and then any other tricks? Or could they have stopped for another reason altogether? Thanks everybody
