Glad you were able to rule out her being egg bound.Update - no egg is stuck. She has not been laying since the cold weather started and I am not sure if she molted as she always looks the same, kind of scruffy. Currently she looks prettier and healthier than ever which is weird. She is not drinking water. I will keep massaging her crop and trying to get her to drink water. Can I treat for worms and coccidiosis without spending the money for a fecal test?
When you were examining her, did you feel the abdomen for bloat/swelling or fluid? You may have to compare her to your other hens. Cup your hand and feel under the vent, between the legs.
Yes, you can treat for worms and Coccidiosis without getting a fecal float.
Corid (Amprolium) is used to treat Coccidiosis. You can find this in the cattle section of Tractor Supply. Dosage 1 1/2 teaspoons Corid powder or 2 teaspoons of 9.6% Corid liquid per gallon of water. Give for 5-7 days - make sure this is the ONLY water available during that time period. Mix a fresh batch at least once a day.
For treating worms a broad spectrum wormer would be good. I would use either Valbazen or Fenbendazole (Safeguard liquid goat wormer) both will take care of most worms. These can be used with Corid.
Valbazen dosage is 0.08ml per pound of weight given orally once, then repeat in 10days.
Fenbendazole dosage is .23ml per pound of weight given orally for 5 days in a row.
In the photos her stance makes me think she has something reproductive going on. Internal Laying, Egg Yolk Peritonitis, cancer, tumors, Salpingitis, etc.
