Breed: Easter Egger Age: 5 years old Symptoms: Lethargic, with gravel in crop I have 20 chickens. They have a 12 x 18 ft coop. They free range in a securely fenced in a one acre field. Fanatic about clean coop, water, feeders. Last wormed (valzaben) in November. Chickens are handled on a daily basis for bug and critter check, and, well, they are just very friendly. Last night when I locked up the coop I noticed she was on the roost instead of her favorite place in the coop rafters. I picked her up she felt lighter than normal. Her crop was full but not hard. No discharge from vent area. (she only lays an occasional egg) This morning she was sitting on the coop floor, not willing to move. Crop was very hard. I gave her 3 ML of olive oil and massaged her crop. An hour later I gave her 3 ML of water (didn't want her to get dehydrated). Massaged crop. One hour later gave her another 3 ML of olive oil and massage crop. When I check on her in an hour her crop was mushy and I can feel Lots of gravel in it. I had one years ago that was impacted with grass so I know what that feels like, this is gravel, not grass. I have continued massaging her crop and giving oil. No improvement at all and she seems weaker. I have her in the garage with a heat lamp on low. OF course she is our favorite chicken! She flies over the fence every day and comes to the back door and clucks loudly until I open the door and give her a piece of banana, then she flies back over the fence. I have no idea why she would be so full of gravel, or why she would eat it when there is grit available in the coop? There isn't a gravel pile or a lot of stones in the field either. I would appreciate any suggestions and help to save her. She looks pretty bad. Thank you!
