I am new. I was given these hens. When the growth feed (unknown brand in a plain white plastic bucket) was given to me with the hens. When it was done I was to start them on laying pellets. They hated the pellets and I changed it to the crumbles. Someone had bloody stool within 2 days of the change. The feed store guy told me to use Sulmet. I did, all was well for about 3 weeks, then I got my first egg on Wednesday! Saturday my Shepherd chased one of my hens up a tree, he did not try to grab her or make any contact with her, but 2 days later (this morning) I went into the coop and there was bloody stool again. Is it possible for bloody stool to be stress induced? All the hens seem fine. They eat, drink, and play in the yard. I am waiting to see what all of your ideas are before I do the Sulmet thing again. We are just dying to use the eggs. How long after do we need to wait to eat the eggs after treating with Sulmet? Is there anything out there that is safe for human consumption that does not take 6 weeks before you can use the eggs??? Thanks in advance for all your help.
