Recently, I found out that my chickens could have a problem with gapeworm And/ Or respiratory disease. Late last night, I noticed one of my chickens did the "gasping" movements a few times and I was horrified - I assume it confirmed that she does come down with something but I have no clue what - I'm new with raising chickens as pet! Some researches, readings I had done, talked about respiratory disease and that the case could be she got gapeworm. So late last night, I administered all of my chickens (3) with Walzine-17 (mixed 1 oz. with 1 gallon of water). I read from many posts to do this for 24 hours period, then wait for 10 days, then do Valbazen for one day. So, my question narrows down to: Because I am not exactly sure if my chickens are experiencing with gapeworm and/ or respiratory disease, can I de-worm them and administer Duramyacin (antibiotic) at the same time? When I say at the same time I meant this: Walzine-17 for 24 hours, then antibiotic for the next 3 days. Then 10 days after the Walzine-17 and 7 days after the antibiotic, administer Valbazen for one day. Does my question make any sense?! I sincerely hope you could give me any input/ guidance/ words of wisdoms on this. Also, is it normal for chickens to breath with an opened mouth? I don't hear any weezing or gurgling sound, yet.... Two of my chickens are probably losing a little bit of weight as well. They are about 3 months old. One chicken is about 8 months old. The one that displays visible "gasping" movement is the 3 months old. Thank you so much!
