I have four Dels of some age, I bought already laying. Anyhow i know their eggs as one lays speckled or spotted eggs. I haven't seen any lately. They are old enough to lay larger eggs. I've checked the yare and found one but not sure who laid it or when. I kept the in the run till 2pm but only found 4 eggs for 22 hens. Is this a light problem? How can I tell how old they are the four that is. The other 18 are only 8mos. old. I have plans to put a light in the coop. How may use lights and does it help. I plan to use a automatice light timeer. How many hours of light would be good? I need more eggs. I have buyers. I alos plan to change out some birds for RIR's as they are better layers. But I WILL NOT GIVE UP MY DELS.
