I've had chickens for several years now, and I'm facing a problem I've never had. For about a year I had my flock free ranging on my property. I had always gotten plenty of eggs. Sometimes it took a few days to find the new spot they where laying, but none the less we always had eggs. I did not give the birds any feed or water the whole time unless it got really dry, then I'd give them a pan of water. They always seemed happy and healthy. This Spring, after I planted my garden, I decided to pen them up so they wouldn't get into our garden. I had a pen with a run already set-up that I had used previously. I cleaned and disinfected it before moving them in their. Egg production immediately slowed down, and eventually came to a halt. At nearly the same time, I bought 20 Buckeye hens from someone, and housed them in a different pen and in a different barn. These 20 laid like crazy for a few weeks, started slowing down, and eventually quit. I've been puzzled about this for some time. Last night as I was filling up their water, I got to thinking that maybe my water is the problem. Does anyone know of something that could be in my water that would cause them to quit laying? It is from a well, and does have high iron. Thanks.
