I have 8 week old chicks that moved out into their coop this week, although they have been going outside for about 5 weeks. Monday I added another chick who was treated for cocci because there was a possibility she had it since the breeder saw reddish poo in their pen. I have also been isolating a roo in a dog cage inside the coop because he is just too aggressive to the new girl. Today I saw red poo in the cage. Not sure if it was from him or one of the others since they decided to roost on top of the dog cage last night. I thought it might be my new girl since there was a chance she had it anyway. But I just saw her poo normally. Can a chick with cocci have red poo then normal poo? Could my roo just be stressed out and pooing red from that? I just went and bought corid and I want to make sure it is correct before I give it to them. It is for bovines, correct? The bag is for huge doses, I only have 6 chickens, does anyone know the right amount to give to them? Any other precautions I should take? I just raked out the coops and cleaned out the dog cage, I was also going to wash all the food and water dishes. Any help would be GREATLY appreciated!! ETA: They have been on medicated feed since day 1.
