I have a problem not sure whats wrong. Looking for some advice. This is our second year of buying chicks from Cackle Hatchery. ALl went well last year. We ordered chicks this year. They will be three weeks old on Wed. All seemed to be going well until this past Friday. We noticed some of them walking "funny". They would just lay around on their sides and just stay there .They wouldnt even get up when we opened the brooder lid to feed them.First it was just a couple of odd and end chicks we got now my little New Hampshire Reds. We got supplement for their water yesterday and added it. Right now we are crossing fingers that the others dont start doing the same things. None have died yet, but they look like they will. Please help, we really appreciate it....
