I’ve got two Brahma chicks that are concerning me for possible marek’s? One is worse than the other. They are both acting like they don’t want to get up and walk around, however they can walk if I pick them up and put them elsewhere. They just don’t stay up very long. The other 7 chicks I have are seemingly fine. Like I said, One seems to be worse than the other and has diarrhea. They will still eat if food is put near them, but they are clearly not getting as much nutrition as the others. I’ve separated 3 of the 9. All 3 are light Brahmas and came from the same batch. I also have buff orpingtons I got a few days prior and they seem to be thriving with no issues. I attached some pictures. The darkest one seems to be the worst off.
