I'm sorry I know this is gross, but I'm worried about 2 of my 6 chicks. I believe they are a week old today (they arrived on Thursday). They have been doing fine, but I noticed earlier 2 of my chicks somehow managed to get their ecrement caked onto their tail ends. I tried to wipe it off with warm water and a baby wipe and seemed to have gotten most off. I checked back on them a few hours later and it is WAY worse! I've tried to get it off and it won't come off. Should I just leave it (it seems like the longer it goes the more is there)? They're so little I didn't know if I should try to bathe them or soak them? Can I use any kind of soap? Should I attempt to just cut it out. I've even tried to like pull and break it apart, but it's not budging and the chick just yelps. This is our first time raising chicks so I am pretty clueless. Thank you!!!
