the last geese we got few yrs ago my wife did not want me to get. well they did not like her and even chased her if she sat by me then would come and stoke necks on my leg.. well this yr she likes em and they follow her like puppies and she just has to clap and they come.. the chicks we have are about 4 weeks now and dont hang with the geese. geese are still brought in for nuther couple days. but we never used heat lamps for geese. and they will go out with chicks soon.
