Chickens need time to figure out the egg laying thing. You may get one tomorrow you might not. BUT in a couple weeks you can expect one everyday for 6 days straight then they will skip a day to reset and then 6 days in a row again so hold on to your eggs you will get there.
I am still waiting for my first Easte Egger to lay, and my second Buff to lay. Right now Im getting two white eggs and one brown a day.
That is the $1 million question...... Maybe you will, don't expect regular laying for at least a couple of weeks as their body gets in to the cycle..... In England by any chance?
