The Cost of Sinus Surgery. by DC on Aug 23 2012 - 16 Comments. In less than three weeks I will be having a septoplasty and endoscopic sinus surgery. I have essentially had a chronic sinus infection for the past eight-plus months, though Iâve had problems off and on for three years.
Chickens experience two, juvenile or mini molts as I like to call them, before a their first annual molt. The first mini molt begins at 6-8 days old and is complete by approximately 4 weeks when the chick's down is replaced by its first feathers.
Hackle feathers: Hackle feathers grow around a chicken's neck and begin to appear as a chicken approaches sexual maturity, around 4-6 months old. A rooster's hackle feathers are long and pointy, a hen's hackle feathers are shorter and more round.
