Hello I have had chickens for about 10 months now. I have one who will be gone by morning. No signs prior to lethargy last night, vaccinated against Mareks, she could walk until today, so I am perplexed. My primary question is that I will have now lost 9 out of 25 birds since July. They have all been sick, some similarly, some differently (One had an impacted crop but never recovered). So it is not as if they have all died of the same thing (none from predators either). Far from it. The last two I lost in the past month, which I attribute to simply not being hearty for the bitter winter. Are these unusual odds? They are well fed, we have a clean coop, change the bedding often, lots of ventilation (it smells nice in there). They get fresh water, good food, nice treats, etc etc. I dont keep it too cold or too warm (we use a heat lamp to keep it above 20F). I have seen no signs of frostbite. I have never seen any issues between the birds, no pecking issues, etc. Do I just seem to have bad luck or should I expect such losses each year? Just curious, I realize no one can know for sure as you dont know the whole situation but I think these seem to be pretty high losses.
