Hi. I have a hen who has been acting weird sometimes since the beginning of winter. My chickens sneeze sometimes and sometimes have a rattling sound in their chest. One of my hens hiccups a LOT and when she drinks she acts like there is something in her throat. She has been acting mostly fine and eats well. I first thought it was gape worm, so I gave them SafeGuard goat wormer today in their water. Now I'm thinking it might be respiratory. I heard it't not good to give tow medicines at once. After the worming is over, if it doesn't help, how long should I wait to give Tylan? Thanks!
