OK...Something's not right. My Marans has a huge... fist sized... red swollen lump below her vent on her bottom. It is soft and squishy. I initially thought she might be eggbound, I've never had an eggbound hen & have never seen what one looks like. The swelling is below the vent. I've heard that eggs can back up & swelling can appear. But does it appear below the vent? The anatomy book says this is the area of the small intestine. I have checked her vent and there are no signs of an egg either broken or intact. I have soaked her in a warm bath for two hours. Lubed her up with olive oil from both ends. She pooped the biggest poo I've ever seen & the swelling seemed to go down a little...But at this point still no egg. Can she poo if she's eggbound? As of now, I'm about 48 hours into this so according to the books if she had egg perotinitis she'd already be dead. Could she just be constipated? I mean really, really, constipated? What should I do next. I have some H2O soluable tylan...does anyone know what dosage I should use. The instructions are for sheep & pigs. Is this the right stuff? I don't normally use antibiotics but think that this looks like something nasty & internal. Ideas anyone?
