I am new to raising chicks and have 8 chicks of various ages 2-4weeks and breeds. I have BO, LavORP, Austraulope, GLW, BCMarans, Barnevelder and 2 SGDorkings. My Dorkings are 2 weeks old and like to peck eyes! They seem to go after my little BCMarans also 2 weeks old and have already split her upper eyelid and damaged her eye, BCMarans does not cry or even try to get away and this is horrifying me to see! I have tried separation with wire in brooder for 2 days and I thought they were over it, but last night started again, so I rounded both their beaks down a little with my dogs rotary nail file so they are not as pointed, also purchased and put in a new black ceramic heat lamp to use instead of the infrared. I thought if it is completely dark they can't see eyes to peck! They don't seem to do this outside, I have been putting them out during the day with the 2 week old ones since they were 1 week old. I put a heat lamp outside with them and they seem like they don't do that outside, but they are too little to be left out at night, so I bring them in when the sun goes down. Last night I had to bring them in a few hours early because it started to rain and then they started picking the BCMarans eye again! Her eye was just starting to open up again, so I am so bummed! What else can I do? The dorkings don't seem mean, just like to peck eyes which is horrible! I see they even try this with the larger chicks! HELP! what else can I do?
