Jersey giants not growing?

[The-White-Elephant]

Hey! Hope you all are having a good day!

Ok. So I have 3 White Jersey giants, and I’m starting to get worried. They are about 8 months old, and they are only about the size of my RIR‘s, maybe slightly bigger. (I’ll post pics). I know they grow big and tall, and should I be worried? (They are all hens)
I added the pic with a Cochin, maybe you can get a better idea about the size.

I feed all of the hens 16% layer pellets, and a bit of whole/cracked corn (depends on which we have).

Thanks in advance for all help! @azygous @Wyorp Rock @Eggcessive

If you're feeding the Giants layer feed, that could be your problem. Growing chickens need protein for skeletal growth, and layer barely has enough protein for laying hens let alone still growing pullets.

The larger breeds don't come anywhere close to being fully grown before one year. They grow a lot between age one and age two, so give them a feed higher in protein and be patient for another year.

You can safely feed an all flock feed to all your flock for the time being. Just make available oyster shell for the layers.

When exactly did you stop to provide the chick starter feed?

Feeding them corn/cracked or whole, will lower the protein percentage of your 16% layer pellets even more.

I stopped feeding the chick starter since they were about 2-3 months old? Something like that

Thank you, I‘ll try! I knew they take longer to grown, but I started worrying, so thanks so much!

Then take the advice @azygous is giving and change their feed to starter/grower with 20% protein.

Alrighty, next time we go to the feed store, I’ll try to get that

Once again, Thanks so much!

And whenever you change their feed, do it over a period of about 7 days, slowly increasing the amount of the new feed.
Abrupt feed changes can lead to molting.

I agree, I would keep them on a higher protein feed, but the "large" dual purpose Gals still seem to grow for the first 18 months or so.
