Look like bulls eyes to me!
I wish I had some determined serama boys!!
Okay, added a little back splash to the wire to cut down on floor debris, and placed the feeder and waterer inside to get an idea for location. Couldn't find any marbles or colored stones laying around the house, so I used small river rock. I'll probably start with the feeder sideways, but this looks like a good location once the chicks are a little older.
I have the long feeders like that but like the round ones better. so they are on a shelf unused chicks like to roost on the long ones a make a mesh . with that little water bowl you don't need marbles . or at least I don't use them .
