I called the cell phone of the poultry director and she was so nice. She told me where to take a dead or dying bird to get a necropsy done, and she also told me the name and number of the county extension poultry vet to call on Monday. She said he will not charge more than $10, if that. I feel much better now, but still heartbroken that my birds are so sick.
She also told me that IB and other respiratory diseases have an incubation period of 10-15 days, so if at all possible to isolate the sick birds and disinfect the coop. I'm going to try to isolate the sick ones in the chicken tractor and then clean out my coop. How should I go about disinfecting the run? It has sand in the bottom but it's very thin so there would be no way to scrape it all out. Do you think it would be alright to mist it with bleach water then put clean sand on top?
