We have 9 chickens and a rooster, all about a year old. We got them as adults about 6-7 weeks ago. Cinnamon queens. They were laying 4-5 eggs a day, a rare 6 eggs a day. A week and a half a go, they gave us 6 eggs, but since then only 2-3 eggs per day, even none yesterday. We did switch to a different feed a week ago, but they were already laying less when we did that. Both feeds are high protein - 20 percent. They have a coop, their own run, and then about 2 weeks ago we started letting them free range in our whole back yard for most of the day. When egg production decreased, I started keeping them in their own run for the morning, but still very few eggs. I have also looked around the yard and their run for other nesting locations, but not found any. They have water and grit/calcium. We haven't changed anything else, so I'm not sure what's going on. I do send the children out to check for eggs periodically throughout the morning, so I don't think anything else is getting in there and eating them. We live in central Texas - a lot of rain last week, but highs in the upper 70s and low 80s. Today was our first upper 80s day, so I don't think it's too hot yet. This is our first time keeping chickens, so I appreciate any suggestions! Thanks!
