Hi my names is Robin I have 4 healthy Rhode Island Reds that we got about 6 months ago and their about 10 months old now. My husband bought 15 ISA Browns chicks a couple wks ago in which we received on last Friday oct 16th. They were born on the 14th and now 5 days old. That afternoon we notice one of them having trouble, laying down alot letting other walk on her and we tried everything we could to help but it's sad to say we lost her that evening. All the rest of the chick's seem very health and happy. But one has caught my attention. She is the smallest and breathes rapidly but eats drinks and runs around with the rest. Of course Ive never owned baby chicks before but it has made me worried that she breathes so fast not lIke any of the others. I keep them warm their bin clean and fresh food and water. I have read other threads but none seems exactly like mine. Today I gave her a few drop of poly de sol no iron to see if it helps. Has anyone experiance this before or have any advise? Also I posted a link video in the little one sleeps and u can see her breathing.
