Okay, I have seen many examples on BYC of 5-gallon buckets being used as nests. Wonder of wonders, I just happen to have several of them sitting in my shed, so you can see where I am going with this. My question is two-fold. First, my chickens are Black Australorp, Buff Orpington, and Barred Rock. The buckets are 12" in diameter, so will that be big enough for these bigger hens to lay in? If the answer is yes, then we can go to the next part of my question. I have room to lay four of the buckets side by side in what I hope will be the nesting area. There would be room for two buckets on top, but they will be very close to the ceiling, with about 18" from the front edge of the bucket to the side of the nesting area, where I will be opening the doors and leaning in to collect the eggs. Will that be enough room for the hens to jump up to the upper layer or will there even be a need for six nests with only 15 hens?
