Okay...so I may have a problem, but I'm not really sure how to handle this one. Got a group of 13 LF reds back in Feb. and have grown them out. Cut the group down to 3 cockerels and 4 pullets to keep back for breeding. Removed one more cockerel to create two trios for fall breeding. All the birds we kept look fantastic, however we have now lost two of the pullets. The first was after a single day show, so we just reintroduced her and the cockerel we showed back to the group, and the second cockerel injured her treading her and she ended up passing. Most recently, we had the birds seperated for fair, and when we returned, we put the cockerel that was at the fair in with the three remaining pullets in a completely different coop and just kept the extra cockerel with the layer flock since he is a good protector. We found one of the pullets again dead (susptected broken neck) yesterday and I have a hunch it was the cockerel again violently treading her for breeding. I've never had a roo get overly rough with the girls, so I'm not really sure what to do. He is by far the better type bird, but out of 13, we are down to a single trio to start our breeding flock, and that leaves us just one coop invasion away from having to start over. We spent almost three years finding the right birds and I'm really not up to starting over, so please feel free to share your thoughts and experiences with this.
