I have 3 bantam cochins who love to go broody on me I have 1 blue and 2 blacks. So the blue went broody last week so I put a fertile silkie egg under her. The egg is developing things are going well etc. Well this morning I went out, I have an 8 hole nesting box. One of my black cochins went broody and the blue is still broody but is now on the top row and the black is on the bottom. The blue was on the egg on the bottom right. She is now on the top middle. So I search for the egg and its not in the bottom right or the top, nope its in the bottom middle with the black hen. My question is, why would they swap spots and now the black is on the egg instead of the blue? Is that normal? This is my first time trying to naturally incubate so I really never paid attention if they moved spots or anything before since there was nothing under them to worry about. I just thought it was odd or maybe I just have odd chickens??
