Yesterday I saw a baby chick for sale, it was somewhat big for a baby chick (still it was definitely a baby chick, around a week old at most) and it was quite active so I thought that it'd be a healthy one. When i got the chick home, which was at night I put it to sleep and turned on a heater for warmth in the room i kept it in. The next day when I got to see the chick in the morning I noticed three things: rattling, wheezing, and occasional sneezing, so it's very easy to imagine the amount of panic I'm currently in. The chick itself is still very active and huggy as heck, it's eating and drinking. it had pasty butt but I've been cleaning it with a cotton swab and warm water. What I've done so far is clean the place I'm keeping it in once more, give it water with a tiny amount of sugar dissolved in it and replace the grains I was giving it as feed with chick feed. I'm currently considering anti biotics but seeing as it looks healthy someone told me that I'm just panicking for no reason. that's why I need to be sure. I have pictures, videos and voice recordings, if anyone here knows about the topic please feel free to ask and I'll send them
