Hi, As a newbie to raising baby chicks I was so excited to read in some of the posts about putting a clump or two of grass, roots, dirt and all into the brooder to help prevent pasty butt, (had to deal with that on day 2). Out to the back yard I went and got 2 nice size clumps and put them into the brooder. All 15 of them loved it and seemed to be snacking on the grass right away!. But now I've read a couple of posts that refer to the possibility of newborns getting a clogged crop and possible getting coccidia? So I immediately took it out, they seemed so sad. Can someone please help me, grass dirt clump to do or not to do. I don't want to add any potential other dangers to their young lives, they are 1 week old now. They are getting non- medicated starter, no grit. I add probiotics and electrolytes to their water. Should I change any of this? Thanks.
