chick not preening and removing pin feathers

[Rowanh16]

this chick is 6 weeks old and i have 8 others the same age. i noticed a wound on her tail area on both sides. it was bleeding so i separated her and brought her in for the night since the other chicks were too curious with the wound and pecking at it. we had had their glass food jar break so we thought maybe that. it was pretty bloody on both sides so i couldn’t quite see what was happening plus my dad handled it since i’m not a fan of blood. looked like some feathers had been cut possibly pulled out i’m not quite sure. she’s all healed now but i’ve noticed a lot of pin feathers around her neck shoulders and chest. she’s pretty shy but so are her two sisters the same breed but i’ve been trying to help her break the little white casing around the feathers after a week of her not doing it herself. she was only seperate overnight and then she was seperate by wire for two days but could still see the others and had one with her. since then she’s been with everyone no seperation and no issues with the wound but just wondering is there a way to teach her to preen these feathers or should i just handle her a lot and do it myself? she’s also a bit smaller but every batch of chicks has a runt so that’s not super concerning to me.

edit: just noticed this chicks wattle is a more developed than the others who don’t have any so is she possibly a rooster and would that have something to do with this?

No need to interfere, the casing will be removed when it's ready. I do agree that you might have a cockerel but that doesn't affect a bird's grooming habits. If you post a picture we can give you an idea if it's a cockerel or not

in the pictures with two chicks the top one is the suspected male and the bottom one is the same breed but a female. we got them as day olds and we were told they were all females but it’s probably hard to tell at a day old. the picture with one chick is where he/she was starting to run so that’s why it loooks a bit funny.

Hmm, certainly seems suspicious, but let's give it a few weeks to say for sure

At this point nothing screams cockerel, but I would give it some more time. The feathers around the head and neck are much harder for them to get to, so not uncommon that they might take longer for the sheaths to come off, but they will eventually.
Any kind of wound that is red or bleeds will attract pecking by others, so a very tiny wound, if they notice it can become much worse. And chicks will peck at anything.

At age 6 weeks, I would say that amount of red wattles is suspicious (chick might be male) but not definitey (chick might be female anyway.)

I agree, a few more weeks will hopefully make the matter much clearer.
