On the UK for the past 4 days we have had really heavy snow reaching nearly 1 foot deep so far and still going strong. Needless to say the chickens only put their foot out of the coop for a second, the problem is there water keeps freezing im going out every few hours to defrost and top-up, anyone got any suggestions? Also do i need to add anything extra t0 their coop at the moment they have shavings on the floor part of the coop and abit of straw in the nest box, i dont like to think its too cold for them as i know it certainly is for me!! Chickens also eating snow, normal behavior??
