Hi all! I had 5 new chicks that I was introducing to my flock. I have 4 older hens and 3 guineas (that adopted my house and I can't get rid of them) in the area where I had the new chicks. The young ones are about 7 weeks old. I had them in their box with a lid on it and placed that into the coop with the others. I was planning to leave them there for about a week or two and then slowly allow them to intermingle. Something happened (still not sure what) and the lid got off the box and two of the chicks were killed and two more were pecked pretty badly. I found them within about 3 hours (we had gone to church... I checked before church and found them like that after). So I immediately got the three remaining young ones back into their box and brought them inside. I cleaned their wounds with saline and doctored with neosporin ointment. One is only pecked on her wing a small amount under that wing... it isn't too bad. The other's whole back is bare of feathers and was bleeding pretty bad from the tail area. The third is not harmed at all. My question is, should I keep the three inside with me and continue doctoring them daily in this manner until they are completely healed and then try to reintroduce them again in the same way (obvioulsy, I will figure out a way to better secure the lid) or should I do something different. I have a feeling it was the guinea's who did the serious damage. I feel so bad. The two that died are constantly on my mind. I keep trying to figure out how the lid got off and why they got so hurt in such a short time. This is obviously my first time of introducing new chicks to the flock. None of the hens I have now have ever been broody.
