Is this Sour Crop, Fungal or a Respiratory infection???! Symptoms: Fowl Breath Sneezing Gooey Eyes some slight gurgling sounds while breathing. Egg production- None- but my girls didnt lay prior to these other two hens the reason why i took these two was for egg production. Coop environment: Muck soil in both outdoor areas, indoor coop has hay and some saw dust. Could moldy hay cause all of this? This has been going on for a few weeks. I culled the two hens that i believe brought it into my coop. 1 of those hens showed symptoms the other did not. If they are not the source of this, i feel bad but i felt i had no other choice. I have a total of 5 Chickens. 2 bantys 1 Silver dorking 1 silver laced 1 production red The only two out of those 5 showing symptoms are my bantams. 1 has all symptoms above the other only has the Fowl Breath and thats it. The rest act completely healthy. Im at a loss. If this a respiratory thing i know i cant treat with antibiotics, but they would be carriers and i don't want my flock to be carriers of this as i intend to Raise and sell Chicks. I will cull if necessary (even though it will break my heart) Do i only need to Cull the sick or all of them even if they are healthy? PLEASE HELP ME SOMEONE I NEED TO MAKE THIS CHOICE TODAY. I DONT WANT IT PASSING ON TO ANYONE ELSE!! Im ready to go home from work and Strip my coop of everything and bleach the heck out of it.
