I lost 2 chickens this past week and not sure why?

I went out to the coop Monday and found one of my buffs had died. Then today my husband found one of our rir dead in the goats pen. Both chickens were my older ones, I got them as laying hens so age is not known. My concern is that they have something that could spread to my other chickens. The weather has been in the 40's one day and in the teens the next. I am thinking this extreme weather my be the cause. Anyone have any expectancy with this?

You could get an autopsy done by the state to determine cause of death and make sure it isn't an infectious disease. If they were older it could just be age and the cold weather probably didn't help either.
