I had a maran rooster show up sneezing. He does appear to have feathers and dirt in his nose. He has shown the sneezing symptoms for about 2 weeks now, he has no other symptoms. I also had a old english game bantam rooster get sick when he was younger with what I think was respiratory, gave him some meds and now he has been better for months, no more sickness. The maran roo was new. The rest of the flock has not shown illness should I be concerned for them? They have been with the bantam for months and the maran two weeks.
