I have six Golden Comet hens myself and let me tell you what I did (advice from my vet):
1. I left all the hens confined together without a rooster for four weeks. Roosters can add stress to hen by badgering her to breed and make her not lay longer. Hens do not respond well to change. Take the Rooster out until all the hens are laying agian
2. Try not to handle them too much if they are not used to it. The distress call they often make while being handeled stresses the others as well.
3. Hens are not machines, they are mothers they will only lay in a place they consider safe enough for the chicks survival. If the toof leaks alot or the nests get wet or have old or no bedding in them. The hen will not lay. The maternal instinct in chickens is so strong that they will shut off there body systems in order to ensure chick survival. They must feel safe, secure and be healthy to lay.
4. Sex-Link chickens, like the Golden Comet prefer to nest in a place that is fairly private and dark. Try adding a top to the nest box to darken it.
5. Provide them with a 16-20% protien Layers Pellets. Also provide them with free choice Oyster Shells and avoid layers scratches because it often is wasted more than consumed. Remember, if your hens are confined, they need as much fruits and vegatables you have left from meals. Even treat them with some worms for added protien. I also pick green grass for my girls. Try to provide everything they would get if they were free-ranged.
6. After Four weeks (or after they all start laying agian) let them free-range, if possible, during the day and leave the coop open. If the hens go into the coop to lay then you did well, This means they feel like the home you provided is safe and secure and they are happy with it. At this point you can return the Rooster.
I hope this helps!
THIS WORKS! I PROMISE! MY HENS WERE TWO AT THE TIME AND THEY ALL STARTED LAYING AGIAN USING THIS TECHNIQUE.
Passing on the best advice I ever got!
