I don't know if it has anything to do with the copious amount of eggs that I am getting from my girls but I do daily give them sprouted oats (along with sprouted bird seed/BOSS, sprouted wheat, sprouted barley) and cayene pepper mixed in wet layer pellets.Hi Nikki!
Red Pepper flakes and sprouted oats are supposed to increase laying. Maybe try giving them some. the red pepper is a small amount--a table spoon mixed into their feed.
Chickens do not have taste receptors for peppers, so they will not feel heat.
