bantam with diarrhoea?Help please.

My black bantam has white on hear rear feathers and appears to have firm droppings but with extra liquid. She has not laid for several days. Does she have diarrhoea? what should i do ?Since i am a newbie i would be very grateful for any advice. Thanks.

Thanks for that . Checked the poo-seems ok. Sorry to ask but how do i check if she is egg bound?

Thanks. I will go and check her. She is never keen on being handled ,unlike my other 3 ,so should be interesting!
