We are raising 5 BRs in urban setting (1/3 acre). We have squirrel, ground hog and chipmunk problem as it is. We may go on a week vacation in winter. Options: 1. Leave the feed out and let chickens and other animals sort it out - concerns that chipmunks/squirrels will finish feed in couple of days 2. Build / but automated feed dispenser - expensive. 3. Build mechanical feed dispenser that chickens need to learn to use - saw picture/plan on these forums. 4. Ask someone to attend daily and feed them - need to bother others and have to give them keys etc. Wondering how others have dealt with feeding in similar situation.
