Thanks, Nancy! I've never seen any evidence of predators, but that doesn't mean we don't have any. I've also tried the golf ball trick...I used ping pong balls. They kicked them all out, kicked them underneath, and "played" with them down there.
I've also tried it without curtains...didn't seem to make a huge difference - if anything i believe they prefer to have them for privacy. My EEs took the longest to lay as well. From my three - the last week - we've have at least one blue or green per day...one day two!
7 eggs today (and another blue). Yesterday was 8...things are starting I look up!
