I had posted a few times- my eater egger was ill and had been showing signs which seem to have a couple different possibilities....but she's great now, and if it had been egg binding, she wouldn't be, as no egg was passed. And she has clearly responded to the corid. So of course now I want to prevent this again..........I am a decent keeper of cleanliness In the coop, but obviously something happaened....I wanted to add that I had recently visited a friends chicken coop to see her set up, and "tour" her barn area, wearing the same boots I wear to work in my coop and yard area. I read that it's possible their "normal" chicken bacteria can be transferred in this way, making my chickens ill, as it's not what they are naturally immune to. (And vice versa so I need to check in with her). Obviously I can't be sure how she got it but I will disinfect my boots before and after visiting another place. Coincidentally I do think my EE is also getting ready to lay her fisrt egg, which I think can go on for days or longer.......squatting, bright red face and comb. But he drastic improvement after a couple days on the corid tells me it was most likely cocci.
