Still no pips in the incubator, but when I checked on the chickens today hen was still sitting on her eggs! She starting sitting on them last night and I figured she was just laying, but this morning I noticed she wasn't in the yard with the others like usual. I went out to the coop to see if she was in there and alright, luckily she was fine and still on her eggs, but there was this weird egg that I did not see yesterday that had a pretty large dark brown spot where the air sac is and she seemed to have peeked at it and pushed it to the door of the coop. Any ideas about the eggs in the incubator, the possible broody hen, and the strange egg?
