My husband and I did our first 3 CX this year (huge number huh?) I had no idea what to expect. They were in a very large brooder with 6 Golden Comet pullets, 3 silkies, and 3 Buff Orpingtons. Because of our location (Northern NY) we had to leave them in the brooder longer than we wanted. By the time it was warm enough for them to go outside, they were almost 5 weeks and we had to cull one of them. Once they were outside they got around and foraged just as our others did. They were hilarious to watch and were much friendlier than any of our other birds. We let them go until they were roughly 14 weeks.. Not sure what they weighed as we skinned them and removed breasts, thighs and legs off the carcass. I know that next year we will buy them later, turn them out earlier, and I will let them rest in the fridge longer. Is it ok to vacuum seal them, and then let them rest in the fridge for a couple days??
