Help with gendering chicklings

[Wordslikeacharm]

Hello everyone, sorry in advance for the long post. I have a bunch of chickens, and this year I got 12 new tiny ones. I will post pictures and descriptions but some of the pics are not the best due to the fact that they don't really stand still for long. They are quite energetic.

1) this one is from a friend who hatched eggs, he doesn't know much about the breed or anything. This one is 3 months old like all the other whites. The only other info he gave is that they are supposedly for meat production (which since we don't eat them, does not matter much). They are growing incredibly fast and seem to have a more delicate health than others. I call this one "Lady Cocca".

2) This is also 3 months old, and I personally think it's a boy but I'm too new to chickens to be sure; currently he's named Jack. Also this unknown breed, unknown sex.

3) This one is Quasi, 3 months old. She (maybe?) has a crooked neck since a month (vitamins, antibiotic, everything tried), she walks, eats and does everything as normal tho.

4) No name yet, this one is also 3 months old, loves to rest on my leg when I sit down

5) another 3mo old white, still no name

6) THE boy. Johnny, 3mo old. I am fairly sure this one is a male, he greeted me with the stereotypical sound of roosters this morning

7) Fanta, the bubbly chicken. She (he?) is affectionate, funny and very curious.

8) My injured baby, white, three months old, she was attacked by Johnny (n.6) and she couldn't really get up. Today she's all better but I'm keeping her separate from the others. Maybe a girl. I don't know, that's why I'm here

9-10-11-12) The brahma babies! They are four, 2 black 1 yellowish, 1 brownish, they are 2 months old and never ever stand still for more than a second so the pictures are the worst but I can't do better at this time. Any clue would be really appreciated.

There it is, all the babies, I am grateful for any input on what they may be (and help with the naming of the white ones would be appreciated too!)

Thank you

2,6,7 are male others may be as well in the 3 month olds. Guessing 11 is a boy as well.
1 and 5 breed may be a factor.

I'm not that familiar with meat birds. I understand that you might not be planning to eat them, but being meat birds still affects the care and lifespan of them. Please research this more.

Hi @Yardmom and thanks for your comment. I will research more on that. What I've been told is they have accelerated growth and shorter lifespan, so I'm giving them a special food with vitamins/supplements to help with that. But you are right, I should learn more about them to be sure that however long or short their life will be they will be happy and healthy.

Looks that way to me. White birds do appear to be 'meat' birds, perhaps Cornish X. Health issues and shortened lifespan are likely for them.

Thank you as well @sourland ! May I ask what shows 11 is a male? I would like to learn that.
And yes, the white ones seem really delicate in health compared to the others. They are all free ranging but I also give them food and healthy treats regularly (appropriate fruits, veggies from our garden and so on). The white ones tend to be around the feeder almost all the time, while the others go around, explore and play more.
