It is possible for chickens to be leery of new things. They are creatures of habit. And so any change can be stressful even if it's for the better.UPDATE: the car got pulled out of the shed with (amazingly) minimal damage and I was able to drive into town to get some cocci treatment, I treated him as such he still refuses water so I had to administer orally. I offered him water and he still refused, he was still really thirsty so I grabbed a container that happened to be the one he used as a chick, and he drank (though not much) from it when I offered (but he still wont get down to eat or drink himself so you have to offer it up), not sure why he drinks from a tiny chick drinker and not a bowl, could it be that its familiar and comforting in this huge stressful change? is it even possible for chickens to have a 'comfort' drinker?? since he hadn't drunk in days his poos were very dry, I've yet to see any more blood.
Glad your car isn't too bad.
I would push water every half hour while I was awake. Dehydration impacts ALL system functions. I would even mix the corid with electrolytes if what you say is true. To push water, I drip drop just below the nostrils and when it roll around into the mouth they usually gobble and swallow instinctively. Most of my experience is with chicks in the water pushing department though.
Simple electrolyte recipe..
2 cups warm water, 2 Tablespoon brown sugar preferred (or white), 1/2 teaspoon EACH salt and baking soda. ( same, if you have it.. salt substitute aka potassium chloride). Stir until dissolved and serve full strength. In this instance IF dehydration IS a serious factor (and I assure always dehydration IS a serious factor) then I would add those ingredients to the Corid water.
Is the chick waterer still have cocci treatment in it or plain water?
