We've had four flocks in the last six years or so...and we know a little bit about the feathered egg machines...
One hint for those of you who have chickens past 18-20 weeks and not laying, it's important to switch from starter/grower to layer feed when you see the first egg or when 18 weeks rolls around.
I keep a written history of when the chicks were purchased, when they first start laying and how long they lay...if you are detail oriented, you can get little plastic leg bands with numbers and keep track of individual hens, although we gave that up after the first year and took a more casual approach....
Most all of our flocks started laying between 17-22 weeks after hatching....
We let our flock out during the day and they coop up at dark and we then lock the coop door and pen door for the evening. They can push the little coop entry door in the morning and will feed and water in the pen till we let them out.
The eggs are tasty, beautiful brown eggs with a dark orange center.
One thing you can do for treats if you have a bait shop nearby, get crickets....they will go nuts for crickets....I have a couple of hens who will fly up and perch on my shoulders and arms to get at the crickets sooner than the rest...
Right now we have 18....9 Golden Orbs and 9 white barred rocks, both brown egg layers.
Oh by the by, our chicken bible is Storey's Guide to Raising Chickens....excellent book full of good info.....
