Cover your heart strings, because I am caluse when it comes to controllable genetic defects.

While I do not think you will be putting down your chick, it is really the right thing to do. That chicken will require extra care. That equates to depending on you or your children to constantly fix its beak to be able to survive or live close to "normal." Children often do not keep up with this. Heck, even some adults can't keep up with it. But this is not the real reason for putting it down.

The real reason is the fact that this bird is genetically predisposed to dying. And it is genetically predisposed to effecting future generations of birds. If she has the ability to lay fertile eggs, there is a high probability (probably 100%) that she will pass on the genes if her eggs are hatched. And because the gene can act recessive, the gene can propogate unseen through a whole line. The immediate response from people is "well, I would never breed her anyways." The fact is, many do get bred and many do hatch out future generations of defects.

With this said, every chicken has a bad gene waiting to come out and we don't put down every bird. The point is, this defect comes out a lot and it is a bad one.

As breeders of poultry we all have a responsibility to propagate healthy chickens that can self-propogate without a lot of assistence. Mother nature teaches us that this is what has to be. We create many birds that would never make it in the wild and we don't put them down, so why these birds? The reason is simple, it has a severe well-known genetic mutation that can be controlled by selective breeding and culling. Every time we reduce the number of "bad" genes, we create a more secure environment for future generations of birds. Had the breeder of your chicks followed this procedure, we would not even have to waste our time talking about it and you would have a complete flock of healthy birds.

Good luck with it if you decide to keep it. Hopefully it will never have chicks. I would also inform the breeder that they are hatching out chicks with cross-beaks. They need to know this so they can fix their breeding program.
