What does this stool mean?

[Delta_the_chicken]

I have two chicks that are two weeks old and one (maybe both) of them has been having foamy poop, on and off, for the past week. Is this an indicator of Salmonella? If so, what do I do?

The same one having problems was having trouble emptying her crop but tonight when I checked it was empty so maybe it was just that she wasn't getting enough food to her poop so she was just pooping air...

I have also been kissing them which I guess I'm not supposed to do

Yellower one is Dizzy Jr. the one with the issues, other one is Mocha. They came from the last eggs of my favorite chicken Delta who passed at 6 months old (eggbound) and so I really want these chicks to be oK.

What are you feeding them? Be specific.
Feed, treats or anything etc...

Yes, stop kissing them, you'll give them a complex.

I am not an expert.

My personal experience is that those stools on the photos are normal stools. Adult chickens poops these a few times a day.

Regular adult bubble stools mean worms. I had chicks in the past had bubble stools once in awhile, I just monitor them and they did not do it often so I did not take action.

Looks like normal poop to me. I kiss my chickens all the time. Drives my husband crazy lol most of them come for snuggles and kisses.
