My aunt really spoils her chickens and says her eggs are huge. I have read, that if you feed your chickens too much, they will lay eggs that are so big it is difficult for hens to pass. How big is too big? If forming the shell takes the most time out of the laying process, (20 of 24 hours) then how may hens lay more than one egg a day? The shell gland supports more than one egg? Would the difficulty in laying large eggs be before or after this process? Also, I just read on post "Hen laying way too big of eggs - How to help?" that possibly less protein, more digestible energy would help with smalled eggs. Would more DE and less protein be better in the winter? I am trying to find a diet that have full potential for the price. On the same post topic was "black oil sunflower seeds oil helping pass egg?" any truth to this?
