We are new to raising chickens and need help. We decided on standard buff Cochins and silkies. We picked up 4 Cochins at the plagal farm and garden on Friday and the chicks seemed to be doing quite well. Eating and drinking and very cute. Yesterday we noticed pasting on a couple of rear ends so we cleaned them and put them back for the night. This morning I woke up to one dead babe and two with pasted ends again. We cleaned them and an hour later noticed to very smelly bloody looking stools. Are we doing something wrong? We received advice to feed them medicated chick starter and vitamins in their water and are doing that. Please help. We are raising them to be pets and don't want to lose them all or pass on an illness to the silkies that we are picking up.
