I ordered my first batch of 30 meat birds (cornish crosses) that are due to be shipped 3/30 for a BBQ we're planning around mid-May or so. My plan is to keep them in two brooders I have, one is 7'X4' and the other is 5'X3' for a total of 43 square feet until they're ready to butcher in 6 weeks. At first I was thinking to build a small coop and run for them but if they'll be ready in 6 weeks as advertised then I think I can get by just using the brooders. I'm new to raising chickens and I'm about 4 weeks into my first laying flock so I don't have a lot of experience to draw on. So do you think I'd be ok to leave them in the brooders till the BBQ or will they be too big and have to go in a coop before they reach 6 weeks since they probably grow a lot faster than laying hens? Any info would be greatly appreciated.
