Well here is my STUPIED story, we have a water trough because our chickens share a 1 acre area with 2 goats and 2 sheep. I don't know how many time I have told my DH we need to chick proof that I swear I have said it 50 times and thought it in my head a million. Well we waited on day to late we had a chick fall in and drown. I was so mad at myself and I knew better! Things just kept getting busy and I just did not do it. Well what a bad lesson we learned. So please if you have a water trough and you have not chick proofed it please do, so you don't learn the hard way like we did. I lined it with very small chicken wire so if someone falls in they can just walk out, and the animals can still drink from it.
