Hello, Our family is jumping into raising chickens this year for the first time. We picked up 9 baby chicks on April 10 - even though we only planned to go with 6-8 (2 Black Australorps, 1 Standard Pheasant Cochin, 2 Barred Rock, 2 Buff Orpington and 2 Welsummers) We started them on medicated chick starter feed and Apple Cider Vinegar water. On April 13 we notice bloody poop, and research led us to believe we may need to be concerned about Coccidiosis. So we stopped ACV and started using a bit of Corrid in the water - using dosage suggestions we found in BYC. On April 15, one of our Buff Orpington Chicks passed away. She was very weak and lethargic. We tried feeding her and getting her to drink water, but nothing seemed to work. On April 17, we picked up another Buff Orpington (so the one that was left would have a "twin") and we also picked up a Standard Silver Laced Cochin. So the Pheasant Cochin would have a "twin". April 17 we also switched to Organic Chick Starter feed, after seeing something that talked about how Corrid should not be used with medicated feed. We also switched the water to using Life Lytes in it for a few days. Since the middle of last week we have been keeping an eye on one of our Welsummer chicks. She seems to have a hard time getting around and is definitely not very active compared to the other 9. Compared to the Buff Orpington we lost, this Welsummer does stand and walk a bit to drink water and eat food. She also eats out of our hand and drinks some water while being held. But she is very tiny compared to the other Welsummer we got at the same time. (as you can see in the picture below.) It is almost as if she hasn't grown in the week and a half that we have had her. She is so tiny compared to her "sister" to her left. We tried giving her nutria-drench today. We think she may have feet that are "sore" or that it is hard for her to walk, but would that really impact her growth? We don't want to lose a second chick within the first two weeks! Please let us know if you have any suggestions. Thank you very much!
