I had 3 hens that layed eggs just fine. Then In july, I purchased 5 more laying hens. I got eggs for the first couple of days and I haven't had an egg since mid July. WHY????? I thought it was stress related and I gave them plenty to stay busy with. Then it got hot and muggy and I thought they were just too hot- gave them ice and a fan. Then I thought it was molting time- but didn't see a lot of feathers. (I now know I was wrong because they later molted) Then I thought they maybe weren't getting enough sun and I bought them a heat lamp (because it's getting cold at nights now) and a uv lamp. It's been 2 1/2 - 3 weeks since I gave them the UV lamp and still no eggs. I've checked and checked and checked for signs that they are eating their eggs or that a critter was getting in and taking them. I put hay in their nest boxes. I have nest boxes with no hay (just in case) They eat layer pellets, and I mix in dried meal worms, cracked corn, and grains. They also get fruits/veggies almost every day. So... Either these hens need to start laying or I'm going to have a freezer full of chicken. I would prefer that they start laying.
