I have some Silkies that hatched out approx 4 weeks ago. They are doing good except that i noticed yesterday there is bloody poop in the brooder. The blood is bright red, not dark and I thought at first that one of the chicks was injured. Everything online points to coccidiosis... I am in ontario and have absolutely no access to medication without a vet first making a farm call. Although I love my chicks I can't justify paying over $300.00 just for the initial visit. Is there any other alternative to why the blood is in the poop? Should I cull them all to prevent spreading the sickness? Wait and see what happens? They have been getting medicated feed, they were hatched by me and been in the house brooder so no exposure to other birds. they still seem to be eating and drinking, don't seem lethargic.
