Hello All,

I hope someone can give me some advice or an idea of what I have going on. I raise Standard Bred Delaware chickens and I am experiencing something I have never dealt with before. This year I purchased 50 chicks of Delaware’s from 2 different breeders. I had little to no issues with brooding them only loosing 1-2 chicks from each group. I raised them separately from one another and split roosters from hen at 6 weeks of age. So I have 4 different pens set up. What I experienced was, one of the groups of chicks at about 9wks old started to have 1-2 a week within a 24hr period become anemic looking, loose color and then die. When I would handle them after they passed I found they were almost skin and bones even though they were eating and drinking normally just 24hours prior. I didn’t see any blood in any stool just treated with Corvid. The losses seemed to slow slightly after that only loosing 1 every other week. Then The losses spiked again loosing 3-5 a week. Same symptoms again, everything appeared normal would do my nightly checks, birds would look down  would pull them out to isolate then next morning dead. I am at a loss for words and now at 22wks It has started to effect my other set of birds. I am down to the last 15 birds when I started with almost 100. Now I have also raised 450 other birds, of different breeds, this year, same management, feed, water, everything and 0 issues.
