Strangest thing...I have two Serama hens sharing a nest box. The first has been brooding for a good two and half weeks or so now, the other has been in there for a week now. They seem very content to share the box and brooding duties. The second hen is VERY young...to the point that she just started laying, and in my opinion may very well just be brooding to get a break from the roos! Still a sight to see though, two moms sitting on the same batch of eggs...I'm curious to see if they even hatch as much time as they have spent pushed out from the origional broody.
