Hello, I have had my chickens for 2 years in April! I only have 3 , as one of them just fell over and died several months ago, even though she seemed perfectly okay! Now i have a chicken who has mostly stood in one spot all day. She is kind of puffed up, like they do when they are cold, but it is 80 degrees here. She did lay her egg this morning. And she did eat some food. ? She looks beautiful, but definitely acting strange. Not herself
