I do have some bad news. If you recall from prior posts, I lost two chickens to Marek's disease before they started producing eggs. Then some time went by and my remaining two chickens started producing. Well, back on Labor Day, my Barred Rock died. She stopped producing about two weeks prior to that day, but she showed no distress or other symptoms until the day before she died when she became very lethargic. Since that time my remaining chicken has been producing eggs regularly until this week. She seems healthy and activity, but she is not producing any eggs. So, I am worried she is ill as well. Hopefully, she will be okay.
Here's a short video about the coop expansion:
