NEWBIE here! i want to thank all in advance for any advice. i recently was givin a hen unknown of what kind. (gold in color fairly big) and a big RIR rooster. the rooster crows sounds like he is gurgling and the hen has all her feathers off on the back area and i noticed she is staying on roost all day except to eat. i have them seperate from my other 8 hens to be safe. any ideas?
