This is the BEST advice I've been given by ANYONE and beyond anything I've read... I cannot thank you enough. I'll pick up that brooder (even if it's only for a few days as the underneath area isn't ideal in the barn, kind of gross...) and just get them out of the hutch since it's elevated to your point and then let that be the place they go nest in at night... perhaps I leave them all with mom in there for a few days at worse so she goes in there.
Two more questions:
1) Do I leave their food in there with that tiny water & feeder for chicks that I'm using now? As I have a huge water trough as my birds hate the hanging water container and refuse to drink out of it since it's in the 90s. I'm afraid the chicks will drown --- but perhaps I leave them in the brooder with mom until 2 weeks and at that point they're big enough? it's a large trough probably too big for 11 hens and a roo.
2) Ditto with food - can I mix grower and layer together and leave that out for everyone?
This is brilliant - and SO helpful - I cannot thank you enough for this. ~Christy
If you move their location, you may find you need to move them all for a night or two to the new spot, but they'll get it.
You're right to be cautious of the big water trough. Could you add something to it so they cannot drown? Bricks or rocks or something that would allow everyone to drink without the risk of falling in. Two weeks would be a lot less risky than now, but they're still tiny for awhile. My five-week-olds have only just now gotten too big to slip through the fence. I've had chicks large enough to fly up onto the rim of the feed bucket fall in and be unable to free themselves. I'd find some way to make the water shallower.
I actually feed a specialty flock feed for more exotic birds since I have chickens, turkeys and guineas together. All the birds eat it, even the regular old laying hens. I would feed the grower to everyone as the lowest common denominator until the chicks are ready for layer feed.
I make sure there's always one food bowl and waterer within reach of new chicks. You can use their old ones, but mom will show them how to use the big ones.
