Hi there, I'm a first time backyard chicken owner and super excited for this new journey With my family! As we start preparation for our broode I have managed to scroung up some free industrial lighting (400w) should be good for heat and lighting and heat.....? When we wired them up I noticed that the omit a humming sound. Not loud but still evidently there. Will this drive the little chickens nuts? Or will it be like the sound of a fan? Am I doing this right? Yikes! Thank you in advance for your response.
