I have been having the same problem....I am sure I am doing everything right but getting no eggs at all from my Buffs and my Americanas...
My chicks just laid their first eggs ( 3 oout of 5 chicks) 4 days ago and since I have only gotten 1 egg (the same color & size) a day. Is this normal? I have RI Reds, 2 Black Sexlinks & 1 Golden Comet. Fan in the coop, egg layer pellets, fresh water, scratch & just started Oyster Shell.
First off how old are your hens/pullets? They will start laying when they are ready to with some starting earlier than others. Just because one starts laying doesn't mean the others are mature enough to also. My latest bunch of girls that are just begining to lay were from my easter hatch. A few of those girls have developed hugh swollen red combs and big fluffy butts. I've found a few new eggs in that house. My three week older girls are still in the process too, and some of them haven't even started. They will start laying when their bodies are ready for it. Be patient those tiny little eggs will appear soon enough.
