So we have several chickens. One set is a year old, and another set we bought in May of this year. (Back story from 2014) Now last year the girls did fantastic! 2 dozen eggs a day, happy, healthy couldn't ask for a better start! When we got them from Farm and Fleet, they were just a few days old at the time, and did not lose a single bird. My husband, and I got also got 4 Tom Bronze Turkeys, but we got them from Rural King since they were the only ones that had them. The day we got them 2 died just hours after bringing them home. We called Rural King, and they blamed us! To which I called a vet friend of mine, with Rural King on the phone also, and asked "We just got these turkeys maybe 8 hours ago, is there anything I personally could have done that would result in their deaths." I gave her a list of the feeds, supplements, and they're brooder box. She said there is no way I could have killed them in such a short amount of time. Rural King sucked it up, and replaced the 2 turkeys. Guess what, the next day I found the 2 replacements dead as a door nail in the brooder, and the remaining 2 died a few months later! (Fast forward to this year in May.) My Buff hen went Broody, sat on her eggs, but they failed to hatch so my husband, and I looked everywhere for chicks so she would be encouraged to broody next year. Well being May around here it's a bit late in the season, and a lot of stores stop selling in May, the ONLY place left was Rural King. *Ugh* but we gave them another shot. We bought 15 Light Bahamas. 2 died a few days after bringing them home, 2 more died a week after that, and 1 developed Marek's, and I hand raised her inside the house until she passed away at 4 months. Since then, I have found 2 more randomly dead overnight. Last week yet another died. I failed to mention that my year old girls completely stopped laying about 2 weeks after we got the chicks. (Today.) I do my normal routine get up at 5:30AM get my husbands lunch ready, and see him off to work. Make myself some coffee, and poke around the internet until our 3 year old daughter wakes up, usually around 6:30 - 7. By 7:30 we make our rounds with the animals. First we feed, and water the rabbits, and quail in the garage. Then we head to the backyard to the chicken coop. I come around the corner to see my Barred Rock roo slumped over, head down, and not wanting to walk much, but still peaking at the feed on the ground. As I look into the coop there I see 1 New Hampshire Red hen dead, 1 Barred Rock hen dead, and 1 Light Brahma dead! Upon further inspection I see that over half my flock is greatly sick. For months they have not been worth meat, or eggs, and now they are dropping like flies. I called my husband in a panic, and starting discussing culling the entire flock, starting fresh next spring with meat birds. I want to gather some opinions before the final decision. Do you guys think it would just be best to completely start over next year?
