This is my first year EVER at having to keep a red heat lamp in the chicken house for my girls...it has been so cold the past week so had to do something as my chicken house is not insulated...i know i should had insulated it but like i said before i have never had to use a heat lamp~has'nt been this cold in forever and my girls are 'getting older'.....the girls do use the lamp during the day and a few sleep under it at night.......am thinking i may need another one for the rest of the girls as not enough room for 14 and 3 guineas all at one time.... Just wondering if anyone else has or is using a heat lamp for their girls during this cold spell we are having??? Do you know any pros or cons against or for use?? Also i have it tied so it can't fall or catch anything on fire...worse thing to happen i guess is bulb could get broken but i think i have it high enough that girls can't bump it to break it.................. Any good~bad~or indiiferent opinions?? just wondering what you all do for your girls during this frigid weather we're having??
