These are my options, bought a brooder heater..checking it out with thermometer under it..chicks didn’t hatch as of yet. Plastic bin too small for heater.. clawfoot tub is an option. I do have a heat lamp on a pole…thought I had this thought out, obviously I did not. I’m open for suggestions
Any chance of brooding them outdoors in the coop?
Otherwise, I think I'd try the brooder plate in the bathtub at first. If the chicks do not seem warm enough with the brooder plate, try the heat lamp at one end of the bathtub (instead of the brooder plate, or at the same end as the brooder plate).
I would not use the heat lamp with the plastic storage bin. The heat lamp would warm the entire space, making the chicks too hot with nowhere to cool off.
You could also look for a large cardboard box (or make one from several smaller ones), aiming for something the size of your bathtub or larger. Some people have used playpens, dog crates, and a variety of other ways to contain chicks & their mess. I don't know what you have available, but the basic idea is to keep the chicks safe, the correct temperature, and contain as much mess as you can (mess being dust, bedding, droppings, spilled food, and so forth.) A solid bottom and solid sides for at least a foot is good, but an open or screened top is great for ventilation and to keep them from flying out the top next week.
If you raise them inside your house, and do not have dogs or cats or small children, you can make a brooder with things that would not be secure enough outdoors, and would not actually keep out animals or children. That is why things like cardboard boxes can be an option sometimes. (About children: the age of the child matters a lot. Toddlers cannot be trusted unsupervised around chicks, grade-school kids should probably be supervised until you know whether that particular one can reliably be careful, and most teenagers are just as safe as adults around chicks. Of course anyone can trip and fall or drop something, so even adults should be a bit careful.)
