Hair of the Dog

Its been fairly quiet at the hide lately with the usual suspects only. The Red Squirrels are active, chasing one another and gradually their coat is shedding to be replaced by the rich red of the summer months.
I was given some dog hair in a bag so it has been sitting in a corner of the hide for some months. Naturally the plastic bag holding it has been damaged by rodents but its otherwise intact. As soon as I put out the hair the tits - Great, Blue and Coal went for it and teased it before collection and removal. This shows clearly that they have not yet laid their eggs but are close. I'm sure they would advantage of the opportunity of good lining even a few days beforehand - they wont waste a good resource.
