I have 25v 5 week old chickens mix of Black stars, RIRs and Red Stars. They are doing great but I just spent a lot of money on two 3 gallon plastic waters with the screw on tops and they arew roostring on the handles and pooping in their water. I just had 2 1qt waters for a while but the girls are too big for that now and for a week or so they were much cleaner but now they are very dirty with shavings and poop.. They have a roost and some nest boxes too but I can't figure out how to stop them. I have the water that is inside their house on two cement blocks but that does not seem to help. any ideas?
