help! Issue with 3 week old chick pooping

[AEJEfarm]

My chicks are 3 weeks today (WOO) and I have been trying to introduce grit into their diet. They go out daily for about half an hour and rummage in the grass. One of my chicks, a rhode island red has been having trouble pooping... she will ruffle up her feather, make a quick repetitive chirp and strains. the movement is much larger than usual and will be kind of stuck coming out of her vent until she manages to get it all out. I have incorporated apple cider vinegar, but I feel like this is happening because they are rummaging outside and are not being given grit. while not trying to poop, she is happy, hanging out with her fellow chickens and acting normally. This also doesnt occur every time, just every now and then, but when it is a regular poop, she still makes a quick chirp like when she is straining. That being said, I integrated some into their food as well as giving it in a small container on its own. the chicks have shown ZERO interest in it. eating around the grit and just knocking over the other container. I need some advice in dealing with both issues! please help!

If they are foraging they will pick up grit from the ground. I wouldn't worry about getting them to eat it, just have it available. Some chickens poop like that. More water consumption can help, so maybe remove the vinegar, she might drink more.

x2 Sometimes chicks don't do well with additives in their water because they won't drink enough if they don't like the taste of it. If you want the others to get ACV, then put a second waterer out there with plain water in it and let them make the choice.
