Out of my five red hens, two of which are aged but who knows how long my record is: Five eggs. This happened once a couple of weeks ago, beginning of August.
I get four eggs 14% of the time in the summer.
I get three 70% of the time in the summer.
I get two eggs 15% of the time in the summer.
Of my three younger red comets (all range from 1 to 2 years old now) I'm still getting eggs even though one is molting. I don't know why.
Perhaps it's what I feed them? I go nuts feeding them. In a week they'll consume
freeze dried mealworms (a tub of 10,000)
blueberries (two or three large packages)
7 large heads romaine lettuce
an average of two or three fresh ears of corn a day
sunflower seed
flax seed
Layena
The regulars such as grit/oyster shell/ etc.
One of the hens, I don't know which, throws out these huge eggs which often have flawed shells. The eggs are so big I had to order different containers to fit them, and the duck containers seem to be big enough.
When it's cold or as a change I'll had Quaker instant oats or farina in there. They're able to graze on my backyard lawn, dig up bugs etc. except during the months of April/May/June/July/Aug when they only go out supervised because stuff is growing out there.
