LOL, you sound like me, I think that at least one of them is working up to a broody. I love taking the eggs out from under them, just to watch them roll them back under, it is so cute.That's a cute description! I love the Cochin's fluffy bussle they look like fancy ladies.
Great pics! Could be they are starting to go broody. I have one that "plays" broody, but has never officially been. She puffs, clucks, has a fit if you look at her in the nesting box, will tuck eggs under her if you give them to her (I admit it, I take the porcelain eggs out of the other nesting boxes and give them to her just so I can watch her greedily tuck them under her - I find it endearing), but......she only stays this way for a couple hours tops. Next day same thing, oh well, maybe one day she will become official.
