Protein dust - chickens and ducks.

Have worked in various forms of farming since the early 60's in UK and elsewhere.
Just a reminder to those who farm chicken or duck.
Protein dust levels from these can be very high, remember / ensure you wear a mask when working with them.

This is for both small and large scale numbers.      Open and especially closed houses.
Also there are various levels of dust too with crops, not so much in this season.
Farmers lung is bad at the best of times even more so now.

Be safe !
