We purchased over 55 chicks in several batches last year. After doing some research about debeaking we decided it was not what we wanted in our backyard flock. Negatives included trouble feeding, loss of weight and that it is not recommended and not necessary.
Several months later we responded to a plea from a family that wanted to close their backyard flock. Half of the hens had been debeaked. Half of the debeaked hens were overly debeaked, affecting feeding.All of these hen were underweight, aggressive and mean and believe me the other hens of the flock gave them wide berth. These hens were nasty.
We set up special feeding stations for these hens as we found if the feeders we were using were low on feed they could not scoop enough feed. It took them several months to recover, they were all in a severe moult, some have had very soft crumbling shells and it took the ones who have recovered over three months to look like healthy hens. Lots of extra protein, cayenne pepper, electrolytes, and vitamins.
In early December half of the debeaked hens had not laid eggs, were still in moult, and we sent them to freezer camp. They dressed out between 2 and 2.75lbs. They have been good for crock pot meals and make great broth.
Make sure that you have enough room for your chicks to brood and as they grow. Allow them to have outside time as soon as they are feathered out and as weather permits. Provide good feed with plenty of protein. Give them attention and stay on top of their behavior and health.
From our experience we would never debeak a chick. Hope this helps you to make your decision.
