1 chicken found dead after not coming back to the coop last night, and this morning i let the flock out and noticed a few were gurgling and making hacking noises (symptoms showed up this morning only) so i started treating them one by one with VetRx and when i grabbed my rooster (he’s a scaredy cat) he started throwing up this clear liquid (about 10-16oz worth) and that’s when i noticed this red thing and white thing.... is this gapeworm or something else!? anyone know?
