My 7 month old Rooster is Sick. I noticed today he wasnt with the girls. I found him sitting under the trailer by himself. My son says he was under there yesterday too,but Im not 100% sure if thats correct. He is just sitting there,not interested in food or water. When he does stand up his tail feathers are down,he doesnt stand long before he nestles himself back down over his legs. His Comb is also a bit purple and he has watery clear diarrhea with green in it.No discharge,no visible problems.Crop is empty.I dont know what to do.I love him so much.I have him inside the house in a kennel, with scratch and hard boiled eggs.Im also giving him vi-tal in his water.He wont eat or drink on his own so Ive given him a little bit by hand. The hens are all fine.Im the only person with chickens in my neighborhood. I dont know what else to do.Any Suggestions?
