11 of my chicks are doing great, then out of the four (2 are much better now and in with the rest of the chicks) that i had problems with and needed a little TLC, 2 are still not 100%. i'm not sure if what i'm looking at is pasty butt, do chicks have a vent and a butt?? is it two different things? this is my first batch from start to finish. i love my peeps and i want to save all of them. the 2 that are in their own separate brooder lay around A LOT more then the others, 1 tries to stand up but has a hard time getting his barings, and the other 1 can stand up but only for a limited amount of time. ive been able to get them to eat a mixure of yogart, boiled egg yolk, and elotrolite water all mashed up kinda soupy, really easy for them to eat. what do i do! how do i get rid of the hard ball on their vent? butt?? thanks!!!!
