Today when I went to feed the boys I noticed Blue's sheath was very swollen(I'll post pics at the end). I admit it has been long time since I cleaned it. So I decided to clean it while he was eating.
1 There is an average of 1460 hours of sunlight per year (of a possible 4383) with an average of 3:59 of sunlight per day. 2  It is sunny 33.3% of daylight hours.
We did a study over 10 years ago based on these three stations and found that for Denver if you count every day when the sun came out for at least one hour, that then you could come up with an average of around 300 days of sunshine each year.- In the Denver area there are probably only 30-40 totally overcast days per year, and some of them are even fairly bright -- about 300 days would have at least one hour of sunshine sometime during the day, but only about 115 days per year fit the classic definition of clear. -- Answered by Nolan Doesken (9/03).
