One of our hens died sometime during the night. There was no blood on her and I am a bit concerned. I clean the nesting boxes every day, as well as any droppings on the floor of their coop and they are given fresh water/food every day. They are mostly kept in their confined coop and yard, but, occasionally, we let them out to free range for brief periods. When we let them free range we keep a close eye on them to make sure they stay out of harm's way. I check their droppings every day to see if there are any dramatic changes such as runny droppings or blood. I did not notice that she appeared to be sick, i.e., she did not lay around listless or anything. I am wondering if I need to be concerned about the rest of my hens or their eggs, or could this just be a freak thing. My hens are 7 months old and all the rest appear to be healthy. I do not believe they are overcrowded, either. We now have 19 and keep them in a 4 x 16' area and their fenced in yard is 16 x 16. If anyone has any ideas, I would appreciate your input. Thanks.
