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.
Plus, generally speaking, you will be able to tell by feathers much earlier since roosters don't usually begin to crow until they are 4 or 5 months old. However, we have had roosters wait until a little later, and begin a little sooner, too.
