Just got four slikies yesterday and they were put over night into their new coop...put newspaper down first and this morning when i checked in on them there was some reddish orange goop mixed in to the poop?? I think it is only one of the chickens as it was not all the poop in the coop...They are 14 weeks old. Also, the feathers on some of their feet look worn out or rotten but they are dry... any ideas as to either of these? Worry? or not?
