I had 39 chickens up until about a week ago, 11 are 2yr and the other 28 ar 1 yr, I bought 6 day olds about a week ago. The problem is last Wed I came home from work and found a hen dead in the hen house, but I thought, "Who knows maybe it just happened?" but then today I cam home nad ther was another one lying dead in the floor of the coop. Nothing show to be wrong with them, no damage, they are free rangerws on about 3 acres. Should I be worried? Should we stop eating the eggs? Any thoughts would be appreciated, thanks.
