PLEASE HELP HEN LETHARGIC

[PoppySeedy]

My hen took ages to lay this morning, she did but since then all she's done is sleep. She likes to eat snacks but she isn't drinking much and keeps making high pitch calling noises, her crop is quite hard and I haven't seen her poop yet, I'm really worried what should I do?
