In the past 2 weeks I've had about 15 chicks die out of about 40. They are all Silkies and all from shipped eggs, different breeders. Anyways, I can't see anything wrong with them. They were all active, no pasty butt, no bloody stools.....nothing!!! I give them fresh water 1-2 times a day and complete scrub the water container every day or every other day (in between if its not bad I just give it a good cleaning with my finger) They also have fresh food daily/every other day. They are in fresh bedding inside my house with pine shavings. They have a heat lamp thats above them. I know its not because they are too hot/cold because they aren't "running" from the light or huddling close together to stay warm. I just don't understand what is causing this when they all seemed so healthy???
