What's going on? We have five chickens, 2 buff orpingtons, 2 black australorps and1 americauna and we used to get 4-5 eggs a day but now we only get 1, mayby 2. Is this unusual? They've never done this before and I'm worrying. nobody is molting and all of them seem fine. Just today we got one egg outside in the pen. How do get them to go in the nest box? I've tried plastic eggs, hay, and corn. nothing is working.Help!
