i am worried about even being near my chickens now that i just got covid. i think infecting them is absolutely possible. i believe this is the article amy blake was referring to.

conclusion
these results suggested that emerging sars-cov-2 vocs potentially expand the host range to chickens mainly through ace2 and axl receptors, while nrp1 receptor may rarely participate in the future epidemic of coronavirus disease 2019 in chickens.

wild and domestic poultry has been the subject of inter-species transmission of covs (zhuang et al. 2020). so far, susceptibility to sars-cov-2 has not been reported in avian species. the phylogenetic investigation of pigeon ace-2 receptors showed bounding potential to sars-cov-2 (qiu et al. 2020). however, experimental inoculation with sarscov-2 has not resulted in immunological response or viral replication in poultry, including chickens, turkeys, geese, ducks, quail, and pigeons (mathavarajah and dellaire 2020; schlottau et al. 2020; shi et al. 2020; suarez et al. 2020).

the current covid-19 pandemic, caused by the highly contagious respiratory pathogen sars-cov-2 (severe acute respiratory syndrome coronavirus 2), has already claimed close to three million lives. sars-cov-2 is a zoonotic disease: it emerged from a bat reservoir and it can infect a number of agricultural and companion animal species. sars-cov-2 can cause respiratory and intestinal infections, and potentially systemic multi-organ disease, in both humans and animals. the risk for severe illness and death with covid-19 significantly increases with age, with older adults at highest risk. to combat the pandemic and protect the most susceptible group of older adults, understanding the human-animal interface and its relevance to disease transmission is vitally important. currently high infection numbers are being sustained via human-to-human transmission of sars-cov-2. yet, identifying potential animal reservoirs and potential vectors of the disease will contribute to stronger risk assessment strategies. in this review, the current information about sars-cov-2 infection in animals and the potential spread of sars-cov-2 to humans through contact with domestic animals (including dogs, cats, ferrets, hamsters), agricultural animals (e.g., farmed minks), laboratory animals, wild animals (e.g., deer mice), and zoo animals (felines, non-human primates) are discussed with a special focus on reducing mortality in older adults.

this same thing happened to me this week with my 5 month old chicken and i was thinking that maybe it just has not been experienced enough to confirm for sure! i don’t know, but anything is possible! just a coincidence maybe until it happens to others too?

i don’t know what health issue your flock has, but i assure you, chickens cannot get covid-19. the research indicates that they cannot even be experimentally infected.

chickens can get a coronavirus, but it is not the covid coronavirus. you can’t give it to chickens or get it from them.
