In OVO vaccination

[duluthralphie]

I have been reading a lot of info on in ovo vaccination for Mareks.

I do not have a $50K machine to use.

I am wondering if anyone has tried this on their own by hand. I am thinking poking a hole in the shell (I think above the air sac and dropping the vaccine in might work. At day 18-19 I doubt the hole would kill the chick if the humidity is high in the hatcher.

Any thoughts? I am not going to do this with this hatch, but I might try a hatch just to see what the results would be...

i found a little bit, slight cone shape helps keep from drilling too far. I just twirl it in with my fingers.
I do crafts with them too. Embroidery on eggs.

this is what I have. It is a torch tip drill. . there are various size drill bits inside this holder. This is easier for me to hold on to being s I have carpal tunnel hands
You should be able to get one at any welding supply store.

I have decided this is even more possible than I originally thought.

Those silly call dux people make holes in the eggs all the time which might be why they have such low hatch rates. Of course, that could be the humanity of them trying to save the world from DUX, but I digress.

If they can punch a hole in the egg I should be able to also and get the vaccine in.

I will try to get one of the deranged DUX owners to come here and tell us how they poke the hole in the egg.

From your linked article. .

doesn't look like it would really work to inject the air cell according to this

I would drill a small hole in the middle above the air sac and drop the vaccine onto the membrane.

I am thinking I could seal the drill hole with a piece of tape. But am not sure that would be needed as the humidity would be +-5 of 70.

This is an article I found it lists the areas the vaccine can go, the air sac makes the most sense for an untried person like me with no fancy machine other than a dremil.

Since it recommends doing the vaccination at 18 days of incubation, there is no need to seal the hole that is made for the injection.

I have made the hole into the air cell by gently twisting a tack or small drill bit against the shell by hand. The hole has helped me in hatching shipped Cream Legbar eggs.

Interesting. However, my extra large hand and fingers do not lend themselves to intricate crafts...

Hatching shipped eggs at high altitude it lets the air into the air cell easier than trying to transpire directly through the shell.

That makes sense.

I wonder if I make a hole and dunk the eggs in the vaccine what would happen... besides killing the chicks what could go wrong?

I might have to get some DUX eggs to practice on so there is no loss to mankind if they die..

I am actually doing this too, LOL! Having a broody hatch out eggs/raise chicks has been impossible for me because I have Marek's exposure in my vaccinated flock. I wondered a year ago about in-ovo vaccination and whether that would make motherhood possible for my hens but I haven't had an occasion to test it out until now! My BCM just went broody so I'm going to try in-ovo vaccination on day 18. I picked up 10 fertile eggs today from a friend/fellow BYC member, 3 of which are from a Marek's resistant hen and the rest from vaccinated hatchery hens. I put five of the eggs under her and five in my incubator. I've got the HVT vaccine in the fridge and I'll be candling in a week to check for embryo growth. I plan on vaccinating all in-ovo (manually obviously) and placing all the live chicks from the incubator under her to raise. I found this video a year ago and it's what I plan on following:

I'm so excited that someone else is interested in trying it too!!!! I still have to figure out syringe length requirements and all that jazz. I've got 17 days to get it all planned out, lol!
