I am new to BYC so sorry if this has been covered already. Today was our first snow of the year. We have 2 Pekins and 1 Roan duck. they are 5 months old. In the coop I have put a heated waterer and a food bowl and beefed up their bedding. They usually forage but with the high winds and snow, I keep them fenced in during the day now. Their coop has an infrared heat lamp. How close does that lamp need to be to the ducks be effective? Also, I feed 1/2 pitcher of 16% protien feed and a handful of cracked corn. Is this ok? Do I need to supplement? Thanks for any help.
