I have a Black Australorp, who has always been on the small side, who is just over a year old. Yesterday afternoon/evening she was acting normally. When I went out to secure the coop she and another one of the girls were in nest boxes. I didn't think too much of it since no one had laid that day and sometimes I have an egg waiting for me in the morning when I open up the coop. This morning she is still in the nest box. I lifted her out to see if I could determine if something was going on. I removed the fake egg (which I put in there some weeks ago to encourage them to use both boxes instead of competing for one) and put it just outside the box. She was very warm. I couldn't immediately see anything wrong and I felt her vent thinking she may be egg bound - didn't feel anything. She was craning her neck downward and as soon as I put her back in the nest box she tried to get that fake egg in there with her. I haven't given her a thorough look-over yet, but because she was so warm and tried to get the fake egg back into the box I'm thinking broody. She hadn't laid any of her own eggs though. Her comb and wattles are red and her eyes are open and clear. Does she sound broody?
