Seriously - I've seen that a lot, and it makes me sad. I'm still wrestling with the idea of eating my birds, and if I'm going to eat them I at least want to know I gave them the best life possible and they were happy!
Do they still use the perch right up to the end? Somewhere I read they have trouble with climbing ladders because they get too heavy. How far apart did you space the rungs? How low is the perch - it looks like maybe 8 inches? Sorry for all the questions - I'm just really excited!
You're welcome!
You should not think twice about it. If you want them to be happy and live a good life, you'll do it

Well, to be honest they are my first meat chicks. I have no idea if they will perch until the end!
Ah, my ladder is not correct.. the rungs are too far apart. The chicks still climb, but I will add more rungs to help them - as you said they become heavy with age and I am afraid that in a few weeks they won't be able to jump as much). I will check the height of the perch, I am not sure... 8 inches seems to be it, I can fit am empty yogurt container below the perch and there is maybe an extra inch left (I use the yoghurt container to fill up the food hehe).
