I have: 2 Ameracaunas (that's what the receipt from the farm store says, might just be EEs, for all I know) - Zombie and Ninja, 2 RIR - Chip and Dale, 1 Leghorn - Betty White, 1 golden comet - Sunshine, 1 Plymouth Rock - Rocky.
Betty is the top chicken - she bosses everybody around, even though she is the smallest one in the flock. Rocky is low chicken. They were both bought at the State Fair, they did NOT grow up together, and I'm unsure of how old they are. Betty started laying a couple of days after we brought her home, and lays sporadically. Rocky started about a month ago. The others were all bought in the first week of May, as chicks (a week or so old).
Zombie and Ninja aren't laying yet, and pretty much ignore Rocky when she is in the nest. Chip, Dale, Betty and Sunshine all chase Rocky out of the nest. They did finally let her in this morning after they all decided to go outside, and she laid her egg. There are 3 boxes, one of which they don't seem to like, even though it's exactly like the one they seem to prefer. The other one is slightly different, and they do use it, if the "favorite" one is in use. Rocky will go into the one nobody likes, and they still chase her out of that one, even though they refuse to use it themselves!
I could come up with another box, just like the #2 preferred one, if you folks thought it would help. Generally, everyone lays in the "favorite" box, unless someone just can't hold it any more, then they go to #2.
Thanks!
