I have a Barnevelder Hen (whom we purchased from a Breeder)... well we actually purchased two Barvevelders and Four Orpingtons at approx four months of age... they had feathers missing when we got them. And I am somewhat cutting a long story short here - but two Orpingtons died - one died after two days and the other after four months, now my Barnevelder doesn't seem well... Her sister is doing well and looks healthy but she doesn't seem to be growing as big as her sister...? I have started to feed her separately today and she is eating well enough when I hold the Food Bowl for her, but if its not directly in front of her face she doesn't seem to be able to see it...? she actually walked in to my Dog today who was sitting eating her bone in the Garden... so i thought she may have problems with her sight...her eyes are clear and there is no discharge - but she just doesn't look right sometimes...even though on other days she looks happy enough and is quite vocal... I really love all of my animals - but I hate to see them not at there best... Any Advice would be much appreciated.
