Our power went out yesterday and the heat lamp was off for about an hr. Didn’t think about it wile dealing with other things. By the time we found them most of the chicks were not moving. Brought them in the house got them warmed up and they started moving eating and drinking. 3 did pass away. But now I am noticing the right wing on 3 chicks are swollen... one is bad the rest is just a little? Any thoughts? All eating, drinking and pooping
