We're on our 3rd flock and having problems. Our first flock was made up of a variety of 11 Rhode Island hens (Red and White). They were fully free-range on our 10 acres of woodland with a 64 square foot custom designed and built coop to sleep at night. We had plenty of eggs year round, but because they were free range, they were more susceptible to predators and during our 2nd year, we were down to 4. We usually got about 8 to 9 eggs a day, easily. This year we bought more, cleared some woods, moved the 64 sq ft coop and built a 350 sq ft run for them to stay in to protect them from predators. We also added some roosting bars that they love. The store made a mistake and while we thought we were bringing home more Rhode Island Reds, we actually bought a mixture of Rhode Island Reds and Ameraucanas, plus 2 roosters. One rooster is a RIR, but we have no idea what the other rooster is. That brought the grand total up to 19 chickens, which from what we read was still OK for our size coop. When they were about 7 months old, the RIR's began laying and we were getting about 5 to 6 eggs a day. Around 8 to 9 months old, our Ameraucanas started to lay and we got maybe 2 blue eggs each day. Between this time, we adopted a flock of 2-year-old RIRs. We bought a 2nd coop (although not as big) to make some space until we could build another custom coop. We've had this 3rd flock for a couple of months. We have 22 hens in the big coop and 7 hens in the smaller coop. Now we're getting maybe 1 egg every other day, and we have 29 hens and 2 roosters. I noticed that a few eggs looked wrinkled on the tops, which I've read is a sign of either age or stress. We added a light, we've continued to try to move hens to free up space, we're diligent to keep their coops clean, we haven't changed their diet, we moved the roosters into our garage in case they were stressing out the hens (we didn't have roosters with our first flock) and we don't see any improvement. It's winter, but we live in the South, so while we can have some cold snaps, it's not intensely cold. It's Christmas and the temps this weekend are in the 50s to 60s. I think the coldest it's been was in the 20s a couple of weeks ago and that was considered unusual. At this point, our Ameraucanas haven't laid an egg in about 3 to 4 weeks. Our RIRs are producing one egg every other day. Does this sound reasonable? Our thought at this point is that we're still dealing with overcrowding and need to cull some chickens. Could that be it? And if so, which ones do we cull? If it's possible that we're only dealing with overcrowding, we'll build a second coop. But even with that, 1 egg every other day with 29 hens seems unusual. Our current coop cost about $2000 to build, so if it's not overcrowding, then we don't want to make that kind of investment. Any other ideas?
