thanks for all the information re light and food. I will be providing more light for the chicks I guess, since we don't have long natural light here. just hope the solar batteries hold out!! we are -22 c. today but the sun is shining and it is quite beautiful. all my chicks are in their winter "patio" and having a grand time but did have a coyote out here this morning till my dogs chased it away. pen is pretty tight though and if my determined dogs can't get into it neither can a coyote!! (well, I hope not anyway). and for 15 hours of light, midnight is about right!!
