I have a group of birds that seem to sneeze quite a bit. They look healthy and eat a lot(about 6lbs every 2 days). There are 7 of them (including a rooster) and I get about 4-5 eggs a day (most of them are cochins). Also their poo looks normal. And another thing we have been going through a severe drought and it is very dry. So do yall think anything is wrong or is it just the enviroment bc I cannot find anything and (besides the sneezing) they are doing wonderful. thanks for your help.
