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.
Molting and other causes of feather loss in small poultry flocks (Kansas State University) Factors affecting egg production in backyard chicken flocks (University of Florida) Not all chickens in a flock will be good egg layers. You may need to sort your flock and cull any hens that are not laying.
