i had 4 baby chickens or chickens and 3 of them died from wet pox, the ones that dies were bros and sisters. Wet pox is these yellow bumps that start coming on the chickens face. It usually goes away, if they r big enough to survive it. On chicks the bumps usually cover the nose and sufficate it. So watch out for it. If it goes away it leaves a scab and u shood wash it out w/ warm salt water.
