Black Jersey Giant x White Leghorn

[ve]

I do not know what is blastosperm but when crack an egg I can say is it fertile or not

Dustin, the blastodisc of an infertile egg is just a white dot. When the egg is fertilized, it becomes a blastoderm and the character of it changes, usually visibly, and then has a white ring around it. There are numerous educational sites on the web that show the difference between an infertile and fertile egg, two of which I PMd to you, but there are many others, as well. It is even more pronounced if you sit a fertile egg on the counter for a couple of days, rather than in the fridge.
Trust me, it's true, not making it up.

The reason for this is that the embryo cells start to multiply as the egg passes along the oviduct. After being laid development stops until such time as the temps are correct for development (or not as the case may be).​

This is what one of our Jersey Giant X Pearl Leghorn Cross roosters look like. He was not even a year old yet. They tend to be as tall or taller then my Jersey boys but not as stocky in the body. Nice and heavy though, the hens are about the same size as my jersey girls and lay well.

thanks for the picture! I can't wait to see what my Jersey crosses will look like. I have a batch of black jersey giant x mutt (mom is a RIR and dad was a cream legbar) and I got 1 yellow chick and 5 black chicks. Now at 4 weeks, they are starting to show different feather colors. Your boy is beautiful! I hope I get a couple of good lookers too.

That's okay, they look almost identical it seems. I have heard Jersey giants are good layers, just late maturing. I expect nice big brown eggs eventually! I plan to keep and grow out a few of the crosses, even if only to have some bigger girls for the Giant rooster to be with. I am curious as they are such opposite sides of the spectrum now. Small white flighty girls who are great early layers and GIANT black mellow but slow maturing boy. 


Thanks for the info anyways /img/smilies/smile.png

I have my own jersey giant rooster and he loves the only remaining WLG (the other died egg borne because she had been born with a crooktail.) in about 5 days their 4 eggs in my incubator will hatch. Also ive got some mix with easter eggers and i think giant. Might be my WLG rooster. The description says giants arent broody, but of all my different great layer breeds, only one JG hen has secretly built a nest and layed on it in the woods

Just to share if anyone is wondering. My White Leghorn Rooster mated with my Black Jersey Giant Hen and she hatched 5 eggs.

3 chicks were all black, 1 chick was all white, 1 chick was white as a chick but grew to be a mix of colors.

Only 1 out of the 3 black chicks made it to adulthood (6 months) and she is tiny, the white chick is roughly the same size as a regular White Leghorn. The rooster is the mix color one, he’s fatter than his dad but just as tall.

The two females have started laying and they lay light brown eggs. They are still new at laying so they’re still small eggs.

Here is a picture of the rooster mix. This is an older picture so he’s bigger than this now.

I'm sorry. My brain must have had a hiccup that day.
I read Giant & thought Austalorp. I don't know whether Giants are said to be good layers. Sorry about that.

Fingers crossed they lay like leghorns.

My Jersey Giant (black) cockerel has been giving my White Leghorn girls a workout the last couple days. One has been laying a couple weeks and the other started yesterday. One egg had a break in it today so I cracked it and it was fertile! Go figure.

I don't have plans to hatch any of the Jersey cross babies as I really did not expect him to actually "make it work" with these smaller girls. But apparently he did!

What the heck would a JG/WL cross look like? A really big egg laying machine? A really small poor layer?

Sort of related, can some explain the white gene that is White Leghorn? Is it dominant or recessive? If so, how does it carry up against a blue (andalusian) or red (RIR)?
