Pullet not growing

[bigz1983]

I have a 6 month old Amerucana/Legorn cross pullet that is about the size of a 3 month old pullet.
Her hatch mates of the same breed are normal size, laying eggs and have a tall bright red peacomb.
She was still making baby chick type peeping sounds up until a couple weeks ago but I haven't heard her peeping lately.
She has no comb development and acts sluggish too.
But she still eats and drinks.
Could she have a bad gland like a pubertory gland or something?

Do you have any photos?
What are you feeding?

Hard to know what's going on with her, could be a genetic disorder or some other developmental issue.
Getting a fecal float to see if Coccidiosis and/or worms are part of the problem would be a good idea.
Look her over for lice/mites, make sure her crop is emptying, watch to see if she's being harassed or kept from food.
I would keep her on chick starter or an all flock feed at least until she comes into lay. You can also direct dose her with poultry vitamins once a week to help give a boost.

Some chicks do not develop normally, possibly from failure to thrive, coccidiosis or other possible disease, worms, or an organ problem. Hard to know. Is the chick having any diarrhea or blood in droppings? What are you feeding?

I haven't noticed any diarrhea or blood in her stool but I haven't paid attention.
She is in a big coop with 3 other Amerucana/Legorn mix pullets that are the same age as her 6 months old.
They are laying eggs so I have all of them on 16% egg layer crumble.
She has always been smaller than her hatch mates.

It would not hurt to worm them with Valbazen 0.08 ml per pound orally, and do a week long treatment of Corid for coccidiosis in the water. Repeat the Valbazen dose in 10 days. Or, you could take some of the chick’s fresh droppings in a ziploc bag to your vet to check for parasites.

She is smaller pullet upper right hand side of photo.
The normal size pullet same age and breed as her has a bright red comb and is much larger.

Is she the one in the first photo?
Some just take longer to mature and with her being a backyard mix it's hard to gauge growth even with siblings.
The lethargy would be the most concerning thing to me, I would watch her and consider treating for worms and coccidiosis as suggested to see if that helps.

Yes she is the one in the first photo.
She hasn't grown since she was 3 months old and she's 6 months old now.

Here is a better size comparison.

I think all you can do is see that she's eating/drinking well, consider deworming and treating for coccidiosis, make sure her crop is emptying overnight and look for lice/mites.
A little extra protein like egg, fish or meat may be helpful. If you treat for worms/coccidiosis give her some probiotics and poultry vitamins for a few days after you finish treatment.

They are all cute and of course she especially is because she's a little runty
