My hen has had diahrea for about four days, very watery and green. I noticed her having problems with her head going back and forth. It was suggested that my hen may be adjusting her crop. I just got these hens as 19 week old ready to lay. I put hay down instead of straw and they were eating it, never thought maybe it could cause problems. So I thought maybe it was from that. I since replaced it with straw. I realized that her crop was not emptying over night. So I have been trying to help her with that. I noticed in her poop looks almost like a piece flesh color. I'm pretty sure its not her shedding her intestines. I haven't seen this before. I tried pulling it apart and looked like a tiny worm inside. I decided today to de-worm all the hens. She is now passing very tiny worms. She has been very active and tonight she is fluffed up and not feeling well. I would think this probably would make them feel very good. She would eat her boiled egg yolk with yogurt tonight. She did earlier. The worms are no bigger then the width of a thumb, about 7mm or half and inch long and skinny and a bit red. I have treated her with "Piperazine Dihyrochloride 53%" That is the only treatment I can get her from the feed store. Here is a picture. Thanks.
