Right well I have a white silkie hen sitting on 6 fertile eggs and has been for 8 days , yesterday my other black silkie went broody and is sat right next to my white broody hen but not in a box, when my black one got up for a drink today I checked and she was sat on two eggs but they where eggs from the white hen that went broody 8 days ago as id marked her eggs so they didn't get muddled up. I then but them back ready for her to sit on but before she could even get back from having a drink the white hen got up and pulled them under her I couldn't believe it. Then when the black hen got back she ended up sitting on the white ones head lol now I can't get her to move I've put eggs in the other boxes to try and get the black one to sit in them and all she does is pull the eggs over to the white one box then sits on her head again. I do to know what to do I'm worried that she will suffocate her .
