Yes I have a small breeding group of four breeders. We all got a breeding quad from a breeder in England and we are going to breed on our own for he first few years (still helping each other pick birds etc) and then swop in and out birds to add extra "blood" even though they will still be the same lineYes, that is where the problem lies I suppose.
I hope you can get yours in Ireland on the road to improvement. Do you have a partner or two over there to help you? A Breeding work group seems to really help. You could work on the Barn while others can work on the paint and trim then share chicks every so often.
Work with the same line though.
