Based on what you are saying, it definitely sounds like she's broody. I have Silkies and they do this all of the time. They lay eggs for a while and then turn broody. I have to force them out of the nest to get them out of their "trance state" so that they eat. From what I've read, Silkies are a very broody breed. Gotta love them, as they are so darn cute!!!
It's so true, she is so docile and trance-like when I take her out of the box to get her to eat! They are such gorgeous creatures, so broodiness is a small price to pay for the smile they are always putting on my face - thank you all so much for helping me with this. :)
