Thank you CMV, I have cockerels of 7weeks. Behavior, always sleeping, dropping wings, neck alway inside, weakness & loss of appetite. Symptoms have been for 1week & few days. Other birds are gradually exhibiting the symptoms & i just isolate them. No broken bones & injury & i don't know for sure what may have caused the problem. I give them finishers mash, though they are 7weeks & the drink a coccidiostat (pantacox) & vitamin ( biovit). Last week i saw lots of sticky whitish poop, brownish poop, the normal gray & white poop, lots of bloody poop with long white worms in it, i even bought a dewormer(piperazine), but i have to deworm after 7th week, so they said. I've only used oxifuranvite, its an antibiotics & vitamin, i also use the drugs i mentioned above in thier water. If possible, i would love to treat completely myself else i really need help. I will upload the pictures soon. I use sawdust as the bedding. Thank you very much CMV, I appreciate.
