After her dustbathing session with Poppy the other day, she went back on to the nestbox. I went out with some pasta, called her (and the others), and she came running. After the pasta, she didn't go back on the nest box.
She is now very interested in the incomers, and chases them whenever their paths cross. She doesn't go out of her way to find them to terrorise them, although I am watching out for that.
At the moment, the littlees keep out of her way. As soon as Gloria and Poppy vacate their run, the littlees run in.
The two groups are sleeping separately, and I have no immediate plans to force integration. I can see that, if I do, Fleur (cuckoo marans) will get the brunt of it. The other two are nimble, light, and sprightly, and can fly up and out of trouble. She can't.
I have removed the fencing that separated their two pens though. I'd had the "gate" open for a while anyway. I left the fence up as a potential barrier for the littlees. However, I can see that they might get cornered on it, so I've moved it right out of the way.
Step by step. No rush.
