Hi, We had 3 black australorp hens, about 1 yr old, in a coop in a bamboo thicket in our backyard. They have been laying very well. We've been feeding them laying pellets, oyster shell, and occasional chicken scratch, and fresh water every day. Two days ago I found one dead on the ground in the morning. She hadn't exhibited any sign of sickness before this, and her body didn't seem in bad shape at all. The other 2 still seemed healthy, but this morning we found a second one dead, same situation. The 3rd seems fine for now, though distraught that she's the only hen left I'm trying to figure out what to do before she dies too. This is our first time having chickens - we've had them for about 6 months now. We are in South Carolina so the weather is getting warmer and warmer, but like I've said we provide them water all the time. We were trying a new method of feeding - we made a feeder and filled it with pellets, but some of the pellets sat for so long in there they got moldy, and I'm afraid that may be the issue. I have now taken that feeder out of there, scraped up all the pellets I could in the coop, and put fresh food in there. The only other difference is that 3 days ago somehow a small wild bird got into the coop, and it appears the chickens tore it apart - all we found later in the day were its wings. Perhaps the bird had a disease that was then passed onto my hens. If anyone has any ideas about what has happened to my hens and what I should do to save the last one or prevent this in the future, I'd be very appreciative! I've tried to find answers on other posts, but decided to put my own details to see what people thought. I feel awful about this! Thanks!
