We occasionally get someone on our thread who you can't convince that you do not have to heat your coop, and ventilation is the #1 priority. Last yr someone insisted it was cold, brutal, wasn't taking any chances... It never got below 20 last winter, it was below zero for most of the previous two winters with down to -20 to -30 below zero windchill.
Yeah.... And then their coop burns down.
I also notice that those are the people that are perpetually treating their flock because their flock is perpetually suffering from respiratory ailments.
Minihorse, good to see you!
I had a bunch of grow-outs and the vast majority were stealthily being eaten before I noticed.

After that a weasel got in to two of my coops... Right after I had decided to not keep any backup bantam wheaten ameraucana cockerels... The one I had was stunning... So yep, I got rid of all the rest and Mr. Stunning was killed by the weasel.
I scrambled, and all of the cockerels that I had given away had already been butchered .... Except for one. That one was given back to me, he isn't yet in full adult feather, so I am not sure how good he will be. The day of the weasel attack the girls had laid two eggs before they were killed... Those two eggs are cockerels...
Anyway, my original (now all dead) quad had consisted of excellent specimens, and it was interesting to see how few of the chicks are even slightly close to the quality of their parents.
The pullets from the quad were not lost (they were in different pens), but I sold most... Really only one is any good.
I do have a nice set of Spitz to breed from, and an up-and-coming dark brown leghorn cockerel that is looking good, only one Dominique pullet but she looks good, she laid her first egg today.

I still have milk goats (got them in February), but added one high quality milking kid, and a free snuggle buddy for her.
