My two silkie hens are doing something rather strange (at least it is strange to me!). The white one has been sitting on a nest for just over a week (there are 9 eggs, but I cannot be sure she laid them all). Yesterday afternoon, she got off her nest for a walk round the garden, and the next thing I saw was the black silkie sitting on the eggs! It is possible that some of the eggs are hers,I have no way of knowing. Anyway, this morning the eggs had been divided into two lots (by the hens) and the white was on one lot and the black on the other. Then the black one got off the nest and went into the garden and the white one rolled all the eggs back into the one nest and sat on them. I put a barrier in front of the hen house to stop the black one getting onto the eggs again..... or so I thought - as when I got home half an hour ago, there she was on the nest with the white one! They are sitting back to back (looks like a two headed chicken!), on the eggs. What should I do? Just let them get on with it? Is this usual behaviour? I wondered whether the black one could have realised that some of the eggs are maybe hers so wants to hatch them - or is she just broody? What will happen when the chicks hatch? Any ideas? Many thanks Tilly ps - Have just had a hunt on internet and have seen that there are several threads about this.... so apparently not that unusual... - but what would you advise, leave the second hen or take her off and shut her out?!
