I brought home 20 broilers last Wednesday from the local farm store. I couldn't see them at the store because the sign was blocking the view. When I got them home they were coughing. In hindsight I should have taken them straight back! I started losing them the next day. Have lost 2 and have 2 more that are not looking good. Have them on Duramycin since Sunday evening. 1st day I went w/ the employee's recommendation of 1 tsp /gal of water, but upped it to 1 TBSP Monday and added electrolyte mix to the solution (save a chick brand). As of yesterday my 1 1/2 yr old rooster is sick and I just went out and retrieved my younger roo from the pasture where he was w/ the laying flock, because he is sounding sick,too (sounded ok this morning). This seems to be a quick incubation period disease and is progressing rapidly. The older roo is now sounding gurgly when he breathes. Seems to be eating ok but is starting to seem listless and no longer able to get a decent crow out (he is whistling). Is there any hope for my flock or do I need to get some eggs saved before the hens start showing symptoms, to restart from scratch? Is there anything over the counter that I can get access to quickly and get in them immediately to slow this bug down, not knowing what it is. I thought about sending in a throat swab for culture but at the rate this is going, a few days time to get the culture results will be too late to make a difference. Would prophalactic dosing of Duramycin for the hens be in order? I don't handle them daily so determining who's getting sick will be difficult. There are about 30 of them if it makes any difference. Any help appreciated! Thanks!
