Ralphie, I get those egg swings too - 6 eggs one day, then 13, then 11, then 12, then 5, then 12...... My flock is so mixed in ages, from pullets just starting up to 5 and 6 year olds. I really can't tell who isn't laying yet, either because they haven't started their first eggs, or because they aren't returning to egg laying this year. Yesterday found an egg laying in the run, and one broken on the floor in the coop. Not sure if I have rats running off with them, or new pullets who aren't quite used to egg laying yet. And yes, love love this spring weather. Chickens are so happey to be outside the run - only thing I think about is that the green grass from last fall is a bit long for them to be chowing down on it. don't want any impacted crops - I have a neighbor about a half mile away that has two big dogs that have been showing up with unnerving regularity. Really makes me angry because I can't let them out unless I"m there. His dogs dug under the run about 4 or 5 years ago and took out my flock. He denied they were his though. Now its the grown up pup and her offspring running deer and coming by - can see by prints how often they are here. They don't bother the run anymore (wire laid around it and electric fence) but maybe its time to get that electric fence up and running.
