Swollen feathered leg and foamy yellow poo, HELP?!

[discocoluds]

Please help me, I had posted message below last week about the swollen legs and not had much responses (has nobody ever seen this issue?) and now I have noticed the same chicken is now having yellow foamy poo. Please let me know if these two problems could be related and how to help my chicken. At what point do I have to take her to the vet? I have started supplementing their food with garlic and yogurt (foamy poo started a few days ago before the added diet).

Hi, can somebody help me? I am new to raising chickens and would like help figuring out how to help my Black Copper Maran chicken. I just noticed that her legs are swollen in the feathered area of her leg where there are feather barely poking through and blood on some of them. There doesn't seem to be much redness. I was having a hard time getting a decent photo since she is the shyest of the 4. I have had them since last may (they are 10 months old now) and have treated their coop with Diatomaceous earth and they don't seem to be caused by scaly leg mites since the rest of the leg looks ok; the other chickens' legs look normal too.
Please advise, are these ingrown feathers? is this a common problem with feathered legs? or is it something else? would rubbing Neosporin on the swollen area help?
I am worried and don't want this to develop into a bigger problem. Any input will be great!
Thank you!!

could it be scaly leg mites?

Thank you ChickensRdinos,
I don't think is scaly leg mites as the rest of the leg where there are no feathers seems smooth and it is not swollen. I have also used DE treatments in the coop from the start. The rest of the chickens' legs are normal.
In the photos you can see the feathers trying to come out from the swollen tissue and some bleeding spots. I AM REALLY WORRIED I don't want for this to turn into a bigger issue.
