I have 14 keets hatched by chicken hens last week of August. Starngely, I have one white one out of the bunch and [it] seems smaller than the others. Fortunately for it, my little bantam OEG is its mother & she is about 6 years old, has raised many a brood and is an excellent mother. On these cold mornings, the OEG has been very good at keeping the white one close and warm (and already, she has her five up roosting with her in the rafter tops of the barn - and too high for the other (LF) chickens)-- the 5 keets she hatched seem very loyal to the little Bantam mother hen despite the fact the rest of them are now larger than the OEG. I noticed the white one sleeps under the hen's wing on the roost.
Two other large fowl Buckeye hens are dually caring and raising the other 9 keets but all together & all have free ranged since their first week. I close them up in the coop/barn at night. The keets follow the hens in each night without any problem. The hens are also slow moving and won't leave the keets behind.
