genetic defect or hatching problem?

Biotin is a B vitamin. It is known as vitamin B7, or occasionally as vitamin H.
There are many common foods that are rich in biotin, including egg yolks, milk, poultry, fish, broccoli, spinach, and cauliflower.

There are poultry vitamins and minerals available to add to their water. I use human vitamins, too.

The chick pictured was hatched by me. There were other breeds in the same hatch and none of them have this issue or any other issues. I'll try to take a better picture tomorrow. That picture was taken with my phone while holding the chick with the other hand. I'll have a helper hold the chick and take a pic with my Nikon in the daylight tomorrow. In a previous hatch, these same eggs, again with other breeds in the hatch, I had one come out with a 1/2 prolapsed vent. It's odd, if you look at a vent as having a straight line across - the upper half is prolapsed but the lower half is not. So far the chick seems to be fine. I'm not sure how this will effect the ability to breed or to lay eggs. Obviously not breeding stock, but I will keep it in the laying flock if it's a hen and she is able to lay. Time will tell.

Just took the pictures before we dispatched them. I don't feel comfortable allowing them to breed.

Chick A

Chick B

Vent on a chick that is 7 wks. At the top (I know it's real hard to see in a picture, we took several and this is as good as it gets), it's prolapsed and there is a split that appeared to be a tear when we first noticed it.

Vent on Chick B above. The top of the bent appears partially prolapsed and there is a very small tear that appears to be starting.

I have checked all of the other chicks & breeds that hatched in the hatches with these. There are no others with issues. Of this breed, 5 hatched successfully, and these are three of them.

I'm so upset about this. I bought my birds from a reputable breeder on this site with an expectation that I would have some good breeding stock.

Is this likely to be a trait that the entire flock has or something that is only a problem with the roo that has the curled foot.

I'm trying to figure out if I need to cull the entire flock? Cull the rooster only?

or

Adjust the feed, hatch some more and see what happens?

As stated in past posts to this thread there are 100 reasons for unsound chicks to hatch. The unsound need to be culled out of your flock and not used for breeding.

Tis best to contact the person you bought eggs from and go from there. She/He may not have had any prior issues. It's just a part of good poultry management to find out if it's your incubation methods, diet and flock breeding.

I would NOT cull all my flock nor would I go blaming it on the rooster if I had hatch two chicks that look like this.

Did you try a poly-vi-sol vit. liquid for a few days and see if the vits helped any? The vent issue I can't tell by the post. I do know 100% sound chicks do not always hatch out at times.
