We started raising chicken in March and we have just loved it so far but today I went into my coop this afternoon and one of my chickens we laying in the corner breathing heavy. I went in the house to call my wife and within the ten minutes I came back out and it was dead. I am worried that maybe something was wrong that I didnt notice before. When we started getting the colder temps about 3 weeks ago all 10 of my chickens have stopped laying. Is that to early? Or is there something that I should be looking out for? Thanks for the help.
