I had 6 RIR that were given to me that were laying and very healthy until they started having bloody stools. Suddenly they stopped laying and 4 had died. We went out and bought Corid to treat the remaining 16 chickens for coccidiosis and everything seemed to be going great. Now one of my baby's, a 5 week old buff orpington, No longer seems to be able to stand and I am terrified she may have Mercks disease. She eats, drinks, and is very very alert but cannot stand for any period of time and her wings seem very weak. I have her in a box by herself with a lamp for heat, She has electrolytes in her water along with the corid and is eating a medicated crumble. Is there something I am doing wrong? Is there anything else I could try? And has anyone else had this problem that could give me some advice and some hope please? I ordered a anti biotic terramycin yesterday but I am also scared of over medicating my baby. I am new at this and am beyond in love with this little chicken so any advice would be greatly appreciated, Thank you so much!
