Have 25 6-day old chicks for 4-H project. Got chilled last night (temp under light fell to 75 fahrenheit) for only a few hours. This morning the seem congested (not sneezing and no mucous coming out nasal cavities or eyes). They make a strange noise (not sneezing...kinda like bronchitis or coming from lungs) then the shake their head. About half of the flock has these symptoms. Any thoughts?
Welcome to Chat Doctor. It looks to be lower respiratory tract infection.It is usually due to exposure to cold weather. Start proper antibiotic like among/clavulinic or moxifloxacin. Bronchodilator with aerosol syrup will be helpful. Nsaid with anti-histaminic is required to control the symptoms. Consult your family physician for further guidance and medications.
