I spend time with them every day. Yesterday, they all seemed bright, active and happy. This morning one was dead. She didn't appear to have any injuries. I just want some ideas as to what could have happened. Everyone else is feeling great, and totally enjoyed the extra time outside while I scrubbed out the juvenile pen. I read, on this site, that they can get kidney stones from eating layer crumble too early. Does that have symptoms? I ask because these chickens have been eating it since day one. Before you tell me how crazy I am, let me explain. The very old farmer who we buy our chickens and our feed from, told my husband it would be fine. We only buy organic feed, but it does come as layer or starter feed. Since the man is a man and he's old my husband is completely convinced that he knows what he's talking about. I gave them the benefit of the doubt, but this is the third hen we've lost since we got them at two days old in March. We got a dozen hens last year, fed them starter, and haven't lost one. Could this be the problem? If yes, am I likely to lose all of my little girls? Thanks.
