Hello, Im very new to chickens. I recently bought 20 Rhode Island Reds. Wow what nice friendly chickens! Anways, my question is about weeds. I have been doing a lot of weeding and have been thowing them into my chickens outside area. They seem to love them as they gobble them up all of the time. The only thing is some of them have prickles on them. Is this bad for them? The weeds do not have pesticide or anything like that. In the last month 2 of my chickens have died? Thanks for the advice!
