OK, about 1 month ago i had an older chicken die from something i don't know at first i thought she just died of old age or something like that but befor she died she found the coolest spot possible on the hot day. all of the other chickens were fine and running around so, i new something was wrong with her i left her there the rest of the day but when it was time to close up the chickens she wasn't there so i went and found her in the same spot still alive i carried her to the coop put her in her spot shut the lights off and said my goodbyes to her the next morning she was dead on the coop floor with her legs spread out. that sounds like she was just dieing of old age right. well she was a perfectly healthy chicken and all the other chickens were healthy too. heres another story that is happening now. 3 days ago i noticed something wrong with my hen when i tried to catch her i noticed when she ran i would hear a sound coming from her that sounded like swooshing water. now today she is very lazy and our rooster is very protective and her poop is really runny. yes she is an old chicken but i think there is something else wrong with her. any ideas. i need help befor my other hens go down too.
