Mass found in nesting box?

[TracieH]

I would not treat a hen with antibiotics unless I knew for sure that she is the one that has salpingitis. Hens with that might have a lowered tail position, act lethargic, or have a swollen firm lower belly under the vent. There might be some yellow urates in the dropping. Antibiotics used commonly are enrofloxacin or amoxicillin. Here is where to find enrofloxacin tablets and dosage is 10 mg orally for every 2.2 pounds of weight twice a day for 5 days.
