I have a Buff O that went broody 22 days ago and still no yellow fur balls. She is sitting on her eggs, but when I went to go a collect the other hen eggs, she was sitting on the nesting box next to her original spot. I left those eggs alone and when I check on her she will be on one nest one time and then the other nest another time. Like I said it has been 22 days since she started sitting on the original nest. At what point should I remove her and destroy the eggs????
