Have there been any other changes - changes to the coop/run, new chickens, different feed/treats, etc?
I've found that they are finicky. I usually get 2 eggs/day from my 4 laying hens. But the last month, I've gotten 4 almost every day. I changed their feed recently and added a cockerel. I have no idea if either has affected their laying. Who knows? The girls do, but they aren't saying. If otherwise healthy, I wouldn't worry too much.
@sean_wonder You are a young person, right? I teach high school, and I really can't say enough about how much you impress me. Even your posts are above par, in my opinion. Wish I had classrooms full of clones of you.
I find it very easy to write concisely when I am so passionate about the subject. For example, I know a chicken's heartbeat is 126-137 beats per minute, and their body temperature is 105-107 degrees Fahrenheit, and that eggs are completely void of fecal matter despite what you'd think, and a lot more useless information. It's rare to understand so clearly what one wants to do in life, especially when there's so much pressure to do so at a young age, but I'm sure you've found indulging your students in their passions, even if it is simply making silly videos on social media, allows them to express themselves in surprising ways. I am forever grateful to my English teacher especially-- you can imagine how often I write and talk about chickens in that class alone. I brought eggs in for everyone once before the Great Egg Crisis of the Week of Sept. Ninth. Additionally, I've been reading at college level since the fourth grade, so I suppose when it comes to literature I'm somewhat of a dork.
