i haven't posted here since my flock were chicks, but everything's been going swimmingly. my flock is happy and healthy and beautiful, a bunch of fat, sassy girls and their fearless leader, bob the rooster. about two months ago, i noticed that one of my barred rock pullets, peanut, had cloudy eyes. she was otherwise healthy and fending for herself fine. she seems to have some vision, perhaps seeing shapes or light and dark. she does peck at my hand if i wave it in front of her. the day i discovered peanut's eye problem, i carefully checked over the other sixteen birds and found nothing amiss. eyes were all shiny and perfect. tonight, i picked up one of the barred rocks in passing and noticed cloudy eyes, so i assumed it was peanut. she was making a fuss about being picked up, which was uncharacteristic. a closer look at one of the pullets on the roost revealed that peanut was four feet away and the pullet in my hands was mambo, but there was no doubt about the cloudy eyes. i pulled out my flashlight again and checked out the entire flock again. the rest of the birds had shiny, dark little eyes, no problems there. their diet is exceptional and i'm positive that both birds had full sight as chicks. they've had no exposure to any chemicals and their bedding is peat. there's no ammonia odor whatsoever in the coop, even at floor level and the bedding stays extremely dry. i use a heat lamp in the coop and it's insulated, but it's not hot, just warm enough to keep it comfortable and the water from freezing. so, questions: in the absence of any other symptoms, is it safe to assume that i got some chicks from a bad hatchery strain, particularly since they're both BRs? my flock is a mix of breeds with just four BR girls. is there anything other than poor genetics that would cause this type of asymptomatic blindness? as long as these two are maintaining themselves in the flock, is it best to let them remain in the flock? it's a very peaceful bunch, no fighting or picking at all. any other thoughts on this perplexing development? i'd very much like to hear what some more experienced flock owners think and any advice you might have. i will not be culling any of my pullets, but i won't be breeding them, either.
