I have 25 RIR chicks that are two weeks old. I started them off in 1 "plastic tub brooder" and have spread them out between two boxes. The boxes are about 18" x 36". The photo below is not of my exact chicks, but my brooder is the same design/materials. The question: Are the chicks too crammed? I have never reaised chickens before, so I have no clue of how crammed is too crammed. When sleeping, the look happy and content. But when awake, since they have a fair share of feathers, they seem to do a lot of hopping and "flying" around the box. Brooder has a hard cover on half and a hardware cloth cover on the half where the light is, so they can't escape from the box. I know I have seen "1/2 sq ft per chick" as the recommendation, but have seen few brooder photos that look like they meet this spec. Any suggestions? Nights here still drop below 65 deg., so I am not in a huge rush to put them outside. Irrational fears of a coop fire keep me from installing a heatlamp in the outdoor coop.
