I have a rooster approx. 7=8months old(americana) who started acting funny. He was all puffed up and his tail feathers hanging low. I seperated him, put him under a heat lamp with food and water. He is eating and drinking. His poop the first day looked like he ate a whole bunch of hay,(spagehitti like) but I am guessing Worms?? What type of wormer should I use? I have DE I can put on food, will that be enough?
