I have a 2 1/2 year old production red hen that is not acting right since this morning. She has layed an egg almost every day since i got her at 23 weeks old, but she has not layed an egg for the last 4/5 days. She appeared ok up until this morning when i went to let all the chooks out, she did not come out of the coop and was roosting on the ladder puffed out. I had to rush off to college so did not get a chance to watch her, i have since returned and found her outside with the others and seeming ok. Still no egg from her today. What should i be checking for? i know there is a possibility that she might be egg bound as she has not layed for quite a few days, so how do i know if that is the problem and what else can i check her for?
