Cochin Thread!!!

Oh my gosh!! This is scary! I did google some of the terms you mention, especially Mycoplasma gallisepticum, and I think I understand - my pullet is the product of a disease her dam had at one time? Also, half of her toenails turn up, like pixie toes, instead of curving down. Now I assume that is also a manafestation of the genetic defect? No, I had not planned to breed her, and now I really won't.

But my girl is otherwise healthy herself, right?

She is the picture of health - none of the swollen eyes or respiratory distress that I read about.
- Is she safe to have, and handle?
- Safe to have around the other birds?
- Is it safe to eat her eggs? Those were the things I was not clear about as I read.

Wow! And to think this came from a casual question about what I thought was a cosmetic problem!!!! Thank you for your information.

Okay, so I've tried to find information Mycoplasma gallisepticum. From everything I am finding; this seems to be a bacterial disease, not a gentetic disease. I have raised several chicks from this hen, all have been absolutely beautiful and healthy. All my birds are kept in a clean, healthy enviroment. I work very hard to raise excellent quality birds, have spent a ton of money to make my breeding program as top notch as I can.
I am questioning as to how it is only the dam that can pass on this disease? Also, nothing I have found on the internet mentions the odd feathering.
Does anyone else have any ideas on what the problem might be with this hen? I have never seen anything like it and now I feel terrible that I have bred this bird. The hen has always been in perfect health, is perfectly feathered, has had several beautiful babies that have always been normal. All my eggs are incubated, not set under a broody hen.
I would never sell anyone a chick that I felt was not healthy or abnormal in any way~ Also; I have had the hen since she was just a few months old, she has never been sick in ANY way. She is just a year and a half now.

Twyla, please don't feel bad about this, it's not your fault and nothing that you've done deliberately or neglectfully. I find the discussion fascinating mainly because I've had problems with birds that I wondered about in this way, i.e., genetic problems resulting from disease or vise versa. I was the person that ended up putting down the hen that Mandy was talking about. I did everything I knew to do, talked to all of the people I could think to talk to, and this poor hen did nothing but get progressively and increasingly ill. Strangely enough, sick as she was, every time she became sick I expected someone else to fall ill also. I was afraid that even the limited exposure to the flock before I could isolate her might cause another bird to contract what she had, but she never passed her "disease" on to anyone. I know the breeder that Mandy got the bird from and he is a very good breeder, very well respected and I don't hold him "responsible" for selling a sick or poorly bird. She was perfectly fine when Mandy received her and for quite a long time after that, really she didn't begin to get chronic with her illness until she came to live with me, so I did sort of blame myself for a short time. However, my other birds were and are far to healthy for me to hold on to that for any period of time.
I feel uncomfortable leaving things hanging with you like this, because if I were in your position I would be feeling the same way and experiencing all kinds of self doubt, etc. So again I want to say don't make yourself sick over this, I'm not concerned about selling my birds to you, and I wouldn't hesitate to look to you for a bird if I needed one.
It would be interesting, if you can find someone to do the testing that Beth's friend is suggesting, to get that done, but if you can't find a place to do it, I wonder if you could draw any conclusions about the problem, by doing some test breedings? Sure would like to hear from Craig and Tom on this, maybe it should have been moved over to the genetics thread.

Surely the hen the chick was under is the Mom, huh? Or do you think she stole an egg to sit on? Why not just put her in a quiet private place and let her raise the chick?

I personally don't care for broody raised chicks, they NEVER settle down, and if Gail's set up is anything like mine, even in a "pure" pen with only one variety in it, the egg could still have come from ANY hen that is in that run/pen/coop or whatever. I don't think broodies care what egg they are sitting on as long as they get to set. I've also had hens that I KNOW came in the coop and set with the broody and left her egg right there where the broody could work it in under herself. Kind of like leaving an orphan at the door step.

There are currently 2 hens sharing the same nest - my Mille Fleur, and one of the F1-BLRs. I think they are sharing duties. When I first saw the chick this morning, the BLR was in the back of the box, the MF in the front, and the chick went back under the Mille Fleur.
When I came home tonight, the chick was out of the nest box, and out with the older birds, who seemed to be ignoring it. The MF was still in the nest, but the BLR was out with the chick. The BLR went back in the nest box, and the chick went back in the nest box and disappeared under the BLR.

So, little "BooBoo" (for now!) is either:
1) Golden Laced x Golden Laced,
2) Golden Laced x F1 BLR (Golden Laced x Splash), or
3) Golden Laced x Mille Fleur
Anybody want to take a guess:

Stephanie (fattie) GREAT news!!
woot.gif
Remember when you shipped my my Splash and Lavender Cochins? I told you the Lav hen had layed an egg in the shipping box? I asked you if she had been with a rooster, and you told me she'd been with a MF boy for about a week...I highly doubted that the egg would hatch but what the heck I threw it in the incubator anyway! Monday it pipped, and it didn't make any progress by Tuesday afternoon so I helped it. It is doing just fine now. His feet are a 'lil spread out, but he gets around just fine! He reminds me of a mottled Cochin chick. I will try and get some pictures. What do you think it will color out like Stephanie? I'm so excited I could SCREAM!!

Here's your medical explaination as to why it is the "Dam" line that is affecting the the feathering of this bird:\\

Progressive cytologic changes during the development of delayed feather amelanosis and associated choroidal defects in the DAM chicken line. Newly hatched chicks of the delayed amelanotic (DAM) line have phenotypically normal down pigmentation. Functioning pigment cells are present in the down plumage, choroid, and retinal pigment epithelium. However, histologic and ultrastructural studies reveal that after hatching regenerating feather melanocytes synthesize melanosomes with abnormal, irregularly shaped surfaces and pigmented extensions. Eventually retraction of melanocytic dendrites and clumping of pigment occurs concomitantly with intracellular compartmentalization of the abnormal melanosomes. Melanocyte degeneration is accompanied by the appearance of mononuclear leukocytes (MNLs) in the pulp of the regenerating feathers. Concurrently, melanocytes cease to migrate into the regenerating feather epithelium, and the result is amelanosis. Changes in choroidal melanocytes are first evident as swelling of cell bodies and associated dendrites. Ultrastructurally, the choroidal melanocytes demonstrate increased cytoplasmic material, melanosomal irregularities, retraction of dendrites, melanosome compartmentalization, and eventual necrosis. Concurrently, MNLs arrive and remove the pigment from the choroid. The authors conclude that a basic melanocyte defect precedes the arrival of immunocytes in the delayed cutaneous and choroidal amelanosis in the genetic DAM vitiligo model of the chicken.

Can't say I understand his email b/c you need a medical degree to understand it but, I figured I would share it will you since you asked.

She is cute zil I know what you mean about the tude. I have a silkie named Sassy for that reason. Just does what she wants and is really an independent thinker. Then she had a baby and her baby is named Princess. Same thing with the attitude.

it's all greek to me at this point. I just don't know what to do with my hen now, should I remove her from the rest of my flock? I have no idea where to get her tested. She's always been a very healthy hen, she's beautiful and so sweet, has been my favorite hen so much that she's the only one I ended up keeping from all the birds I ever started out with.
It's very heartbreaking to me, I feel pretty down about this situation. I work so hard for my birds and do everything I can for them to have happy, healthy lives. When something like this happens, it's pretty hard to swallow. Thank you for all your information from your friend. At least I know now not to breed her anymore.​
 
Like the other person said this is information only. You have no way of really know except if you study the Dam's feathering you can see pointiness to them. That would have been the only detection.

Also, in reality you have no way of knowing if a bird in your flock has it without doing the blood test. If you free range your cochins meaning the are not kept in a controlled enviroment, 70% of free ranging birds have or have contracted in their genetic M.G. and like humans the viral and bacterial infections affect poultry and humans differently.

If you can not have her tested then there is no way to really know for sure. If she has been with the flock this whole time there is no point and removing her b/c she has already exposed them.

If it were my hen I would probably keep her but, not breed her knowing her offsring will have DQ's in their feathering and you could be potentially putting other flocks at risk if she is a carrier. So, your state doesn't have a state tester? That stinks if they don't

Thanks Nancy~ I really appreciate your words of encouragement. I jus don't know how to handle the situation now. Sometimes these bumps in the road are pretty big, makes me feel like just saying forget it but then I go out and visit with the birds and watch them for a little while and I know that I just couldn't give them up.

I don't know if we have a state tester or not, I am trying to get in contact with my friend who would know better what to do in this situation. My chickens are not free range, all breeds are kept seperate in their own pens but the outside pens are seperated only by chicken wire.
