I skipped this spring just because of the cold and plan to do fall meaties. Anyway, when I do mine they are in a pen with nothing but shavings, water, and food. I space two heat lamps out and they all huddle together. Pretty sure (since they are pea-brained chickens) they smothered each other like you said. I never use any medicated food or special anything and always do well with about a 5% mortality rate from heart problems (CX, sheesh). I usually only have them on heat for about two weeks (2 weeks inside, 2 weeks on lamps, and 4-6 more weeks on nothing). We average 7-9 lb hens and 9-12 lb roos dressed.
Yeah, it was a LOT warmer last year at this time, and we actually got our birds 3 weeks earlier this year because I didn't want to be dealing with July heat and 8-10wk old birds like I did last year. The only mortality issues we had last year were 2 from shipping stress and then 15ish from neighbor's dogs. Our birds were good sized last year, but not as big as yours! Hoping to be able to grow them an extra week or so to get a little bigger birds this year.......if they stop killing themselves!
I had the same problem a few weeks ago with my meaties. The CornishX are so stupid that they don't get out from under the pile and are smooshed to death. I moved them to a bigger pen. It's harder for them to pile because they can't brace themselves on the walls. I'm really sorry for your loss, its not the same as a pet loss but it's still a financial loss and that hurts too, been there.
Exactly! I guess the silver lining is that it was NOW when I don't have $8+ into each of them for feed. What sucks is that we basically lost 20%. We're planning on moving them into the tractor this weekend (as long as is doesn't RAIN) so they have a little more space and, as you said, less walls to get stuck in.
For those of us mi people do you insulate or do anything special with your coops? Mine is just sided with t1-11 siding think this will be ok in the winter?
You can insulate if you really want to, but it's not necessary. As long as your coop provides good ventilation and no drafts down at bird-level they will be just fine. I housed [juvenile] birds in my meat-bird tractors for most of the winter, and those are just tarps over fencing/framing....and only tarped on 3 sides.
