We bought 10 broiler chicks on Monday (hatched Monday morning), and on Tuesday I noticed one chick sort of sneezing, certainly congested. He does that all the time now, no worse no better. It is Day 3 today. Another baby chick started to do the same. Do you know what's happening? We feed them organic broiler starter, water with kobmucha. They are with a broody hen, in a brand new clean brooder, inside the house. The hen is OK. She hatched one chick a week ago, he is also fine so far (he is in the same brooder). My understanding is that if chicks get infected within a day or two, it must be viral, not bacterial. Is this correct? Can I do anything to help them? Is it contagious? The sneezing babies eat and drink well. They are not lethargic. But they are constantly sneezing. Thank you so much for your help!
