One of my hens has a problem with more than 14 hours light a day, at 15 hours her eggs had a bump around the middle of the egg. I reduced the light to 14 hours and her eggs returned to normal. She will be 3 this spring and needs her rest at night.
My girls (the Roo's too) meat me at the gate/s first thing in the morning (the sun is not up yet, still dark out) and tell me they want out, and most days I let them go. My hens all return to the hen house to lay their egg, kinda funny to watch a hen come running to the chicken yard, over to the water grab a drink and into the hen house to lay her egg. "Oh, oh, oh, I gotta go,,,,,," And the Roo is about 30 feet behind her, and he often waits just outside the hen house, just like an expectant Dad! I give my girls lots of grain (whole), fruits veggies, toasted egg shell and oyster shell, what ever table scraps the dogs dont eat. No egg layer mash/pellets here!
suen46, are your birds (feathers) nice and shinny with bright red combs?
Ever watch a chicken steel a dogs bone? My dogs are very good to put up with it!
