I have 15 chicks that are about 4.5 weeks old, I moved them into their new coop this week (brand new just finished) and I insulated the coop with blue board type insulation. I quickly noticed that they began eating the insulation so i was forced to sheet the inside of the coop but they did manage to eat some insulation before I figured out they were doing this. Well a couple of days later I noticed a spot of blood that I thought might have been poop but I could not find any stool in it, I posted something on here and someone told me unless I saw more not to worry as the blood could've come from anywhere. Today I finished my run and let the chicks outside for the first time for about a half hour or so (with me supervising the entire time) and they all seemed to really enjoy being out, nobody acted sick or lethargic or any different than normal so far as I could tell, but when I was putting them back into the coop I noticed a couple of dried poops on the roost that appeared to have blood in them.
I took a couple of pictures to see if anyone has any advice on if this could've come from the insulation, or possibly coccidiosis, or something else, or something I don't need to worry about? I did see several of my chicks poop while I was watching them (also got pooped on a time or two-yuck) but all of those poops appeared normal and free of blood...I haven't seen any fresh poop with blood since Monday and only 2-3 poops total that had any blood in them...any advice would be appreciated! Thanks!
