I stand at their run which is in garage attached to our house for the full feeding time. No food is left in the run if it takes them too long I multitask(I know not good) read ,dream,plot plan and talk with my birds ..lol. I am in there each and every time. There are no rodents and the quantity of each offering is not an overabundance. I take the bowl(s) out each time to a sink and wash them so nothing remains. Each feeding is completed with a observation of crop and behavior,adjustment of a window if needed that has a screen or at night a light adjustment (40 w )just to balance out light needed for upcoming(we hope egglaying).Garage door is opened when 2 adults are at opening to be sure no predator will get in.I sweep so many times during the day and water container is cleaned of poop and feathers and pine shavings at each feeding time.The water with ACV is changed and scrubbed every morning.Pine shavings added and removed every morning and as needed. I would bet my life on it there are no predators at all.Garbage is placed in the can closed tight and taken out of garage 3x a week. I keep their garbage separate from household. They are Silkies and 18 weeks of age. I admit spoiled but that is not a problem . I am concerned about quanity of food I am not concerned about diet variety as I am addressing that on a daily basis. They lack sufficentsunshine ,they do dust bathe, and that sunshine issue will be resolved very soon.I give 200 percent to them when they need it ,since I am relatively a new SILKIE owner I need to be sure they are thriving. They look good and they are verbal and seem pretty content. Dropping are normal.I know I need to get them in their coop soon so they can continue on to maturity ,lay eggs and get their sunshine.
