This is my first flock of chickens. 3 of them have died in the last 24 hours and I don't know why. The birds have just started to lay and are 6 months old. Before the deaths, I had 25 birds. 11 sex-links, 13 EE's and one Australorp rooster. I have had these birds from day-old chicks and have had no problems with health or diseases. Two birds died last night, and one was found dead and still warm this evening. All the dead birds are Easter Eggers. The birds which died last night were my two lowest ranking. They had bare butts, but they didn't have any real open wounds or anything. My husband theorized that maybe the high-ranking chickens denied them access to water.

My coop is secure. There is no way an animal has gotten into it. It also has good airflow, it has a heat lamp. Though last night and tonight are warm. The birds have unlimited access to DuMour Layer feed and are given fresh water from the same source 2-3 times daily. None of the birds appears to have any health issues. They seem fat, eyes are clear, no growths or spots on their combs. Today, I even brought in a record number of 20 eggs (the birds have only been laying since January 14th). The birds are offered oyster shell in their feed a few times a week (maybe I need to offer it more often?) and are given fresh pine shavings for bedding every week or so. I do feed table scraps when I have them, though I haven't given them anything in a couple days.

One of my theories is that maybe the heat lamp (which has been in use 24/7 for the last 2 weeks or so due to frigid temps) has caused them to die of exhaustion? The bulb is a red 100 watt bulb but it is bright enough that the chickens wake easily when I move around outside after dark. I didn't think this was a problem, but now I wonder. My poor chickens.

Please help me. I'm so sad and I hope that I can prevent anymore of my beloved girls from dying.
 
I had one die out of eight with the exact circustances. No trace of mites, but they had bare butts from being pecked at. I'm going to keep an eye on this thread and see what the BYC family has to say.
 
I'm so sad that nobody seems to be able to help me. Another chicken died today. I checked them as best I know how for lice or mites and I don't see anything. Their crops and vents seem fine.

The hens are all acting fine, but I did note that some of them have very pale faces. They all look a bit more picked-on than normal but otherwise they all seem fine.

If anyone has a suggestion, please offer it!
 
Other possibilities are coccidiosis, though I doubt that if they were raised on that soil, and bad feed. Moldy feed will make their crops stop working and sour, then they basically begin to starve. The only way to know is have a necropsy done on one of them.
 
They haven't been allowed to free range in several weeks. So I know that's not the problem. I don't think coccidiosis is either. But they're pale. And another thing: They're picking at each other like crazy. Today was warm so I let them out for fresh air and hope they'll give each other a break.

How do I check for lice and mites? My husband visually inspected the vent and underside of a dead bird and I visually assessed the living flock members. Nothing looks wrong....

The feed looks fine. It's kept dry and offered fresh every other day. It is kept in an airtight container when it isn't being offered to chickens.
 
If your experiencing birds dying in numbers in a short period of time I would suggest calling a large animal vet. Thy do make house calls. I imagine you would do the same for cat emergency.
 
The state poultry lab could help shed light on this. It's impossible to know for sure just from those symptoms, which are common to several things. If they're picking, how is the protein level in the feed? Does it have animal protein or do they get some from other sources?
