Vaccines build immunity the same way catching the real disease does, except without the full blown disease (& subsequent death, for many diseases). Vaccines and their method of action are far too often misunderstood.
The same immunity is built through (most) vaccines as if the bird had caught...
I don't know if I'm allowed to post links. But here is a video on treating pests on poultry.
Apply "frontline for large dogs" to poultry, by putting 1 tear sized drop at back of neck, under each wing, above vent, and below vent. Use a .25 guage needle syringe to suck the medication out of the...
Self blues are not a standard color in cochins yet, so really none of them are quite show quality yet, so it's a perfect color for you to start with. To improve this color, get a show quality black cochin.
They are not as hard to find as you may think. Check cochins international Facebook...
The partially dominant Andalusian blue (not self blue, which is based on recessive lavender gene) affects black, as you know. A black bird is bl/bl, a blue bird is Bl/bl, and two copies of blue makes splash, Bl/Bl.
If you cross a black bird bl/bl to a blue bird Bl/bl, you will have your...
Most people don't recommend crossing blue to self blue. There are some examples what they look like, I have seen online. But I think they are worth more separately, and pure bred. Especially those self-blues. If you start getting andalusian blue gene in with your lavender lines, you have splash...
The darker skin on Wisteria is interesting. I believe brown-red colors in most breeds are expected to have that "gypsy" face, but I'm not sure about what is expected of brown-red cochins. I think all cochins are supposed to have yellow legs, but it doesn't seem to be that uncommon of a fault...
Oops! I am so sorry. I responded to your post off of my phone, and thought your response was in the lemon blue forum. Of course you know what lavender is. Sorry...
I can't figure out how to edit my previous post or delete it.
Thanks for answering! What you have there is a self blue, yes, based off of two copies of recessive lavender gene on a black bird, with maybe some yellow leakage. Or might be lavender gene on a red brown bird, since lavender will dilute red too. That's a nice color, and rare! Lemon blue can look...
