My chickens just started laying in the last 10 day or so. The 7 Lt Brahmas seem to be having problems. Two of them, I don't know which two, are laying their eggs from the roost at night. I keep finding two small soft eggs under the roost. Is this something that they just need to figure out for them selves. All my other chickens eggs are hard and not soft so I know the calcium is available to them. Is it possible that the eggs are being forced out before they are ready by the chickens need to poop? The eggs are dropping to the ground from the roost about 3 feet so they don't survive the fall even though they are landing in a cloud of poop! Any advise would be appreciated.
