In short: less time consuming than children, more time consuming than a dog.Can't walk or look after a dog properly, can't be trusted being alone with her kids, can't fathom how to do more than 1 small wash load before lunch.
Moans that she has no time to pack because she has small children and says she neglects herself with not getting her hair done, but is apparently being trusted to look after more animals, and rescue chickens at that.
I don't know how time consuming chickens are, but if you can't cope with the basics in life then you shouldn't even consider taking on more!
She will need to:
Clean the coop and run thoroughly once a week (at least)
Clear nest boxes and roost of poo daily
Collect eggs daily
Top up water when needed
Top up feeder when needed
Clean water dispenser and feeder out once a week. Plus spot cleaning as and when.
Regularly check chickens for disease, worm them monthly.
If the coop is smaller, allow the chickens time to roam and forage.
Maintain coop and run so it remains water and pest proof.
