hi I bought and hatched chicken eggs for the first time and apparently one of the chicks what I think is an infected eye it’s 2 days old and was thinking to take it to the vet but turns out to be expensive. I tried cleaning it with water and also dropped so tea in it! Please give me instructions on what to do and how to treat it! It also has a string like thing coming out and not sure if its poop or not I tried pulling it but was scared if they actually had a belly button cord
