I have a bird who had this same problem, she is doing incredibly well, her only limitation is her size and ability. She is growing very slowly, she just started developing tail feathers.
we are raising all of ours for pets and eggs, mainly because we have a vegetarian in the house, and I wouldn't want to butcher chickens we raised in a brooder, and also because we can't have roosters.
We are currently using 2 wyze brand cameras in our brooder to keep tabs on the little nuggets, and are planning on using one in the coop. I will be sure to keep this in mind!
