We have four chickens, 19 weeks old, never laid eggs yet, never wormed (I didn't know we were supposed to...this is our first "flock") This morning 6 a.m. I saw some blood, a little was splattered on the door, so I thought maybe they had a minor tiff last night. Went out later at 10 a.m. and there is much more. (I'll put some pictures of it here. Sorry they're blurry.) Seems to be connected to their droppings. One spot it is very runny-looking (third picture.) They seem healthy and fine...no behavior changes. I just cleaned the coop last night and put in fresh straw; I clean the coop regularly, fresh water last night, so it's not dirty conditions. Also I let them out every day to "free range" around the yard. I read about Cocci on this site, but aren't they too old to get that? I got the impression Cocci occurred to very young chicks? If Anyone can give me some advice about this I will greatly appreciate it. (My husband will not take them to the doctor, so that's out.) Should we buy both wormer medicine and Cocci medicine in case it's one of those? Thanks for any help.
