I am having a similar problem. I have 32 hens and we were getting about 20-25 eggs a day. My flock is a mix of 5 Barred Rock, 4 Buff Orpingtons 13 Ameraucana, 1 Blue Laced Wyandott, and 9 Red legs. We were getting 6-8 Green eggs a day and now only get 1-2 a day. Th production has decreased to 9-11 eggs a day. We have had a lot of heavy spring storms. I had been feeding them a mix of scratch and layer. They seem all healthy and spend most of their time outside of the coop. I am not sure what to do for them. I am wondering if I should switch their feed to just scratch?
